DAVID BRIN

NATULIFE

I KNOW, THINGS TASTE BETTER fresh, not packaged. Hamburger clots your arteries
and hurts the rain forest. We should eat like our stone age ancestors, who dug
roots, got lots of exercise, and always stayed a little hungry. So they say.

Still, I balked when my wife served me termites.

"Come on, sweetheart. Try one. They're delicious."

Gaia already had the hive uncrated and set up by the time I came home. Putting
down my briefcase, I stared at hundreds of the pasty-colored critters scrabbling
under a plastic cover, tending their fat queen, devouring kitchen trimmings,
making themselves right at home in my home.

Gaia offered me a probe made of fine-grained pseudowood. "See? You use this
stick to fish after nice plump ones, like chimpanzees do in the wild!"

I gaped at the insect habitat, filling the last free space between our
veggiehydrator and the meat-sublimate racks. "But . . . we agreed. Our
apartment's too small . . . "

"Oh, sweety, I know you'll just love them. Anyway, don't I need protein and
vitamins for the baby?"

Putting my hand over her swelling belly normally softened any objections I might
have. Only this time my own stomach was in rebellion. "I thought you already got
all that stuff from the Yeast-Beast machine." I pointed to the vat occupying
half of our guest bathroom, venting nutritious vapors from racks of tissue-grown
cutlets.

"That stuff's not natural," Gaia complained with a moue. "Come on, try the real
thing. It's just like they show on the NatuLife Channel!"

"I . . . don't think . . . "

"Watch, I'll show you!"

Gaia passed the stick-probe through a sealed hatch to delve after six-legged
prey, her tongue popping out as she concentrated, quivering with excitement from
her red ponytail down to her rounded belly. "Got one!" she cried, drawing a
twitching insect out the hatch and to her lips.

"You're not seriously . . . " My throat stopped as the termite vanished, head
first.

Bliss crossed Gaia's face. "M-m-m, crunchy!" She smacked, revealing a
still-twitching tail.

I found enough manly dignity to raggedly chastise her.

"Don't . . . talk with your mouth full."

Turning away, I added -- "If you need me, I'll be in my workout room."

Gaia had rearranged our sleep quarters again. Now the cramped chamber merged
seamlessly with a tropical paradise, including raucous bird calls and mist from
a roaring waterfall. The impressive effects made it hard navigating past the
bed, so I ordered the hologram blanked. Silence fell as the vid-wall turned
gray, leaving just the real-life portion of her pocket jungle to contend with --
a tangle of potted plants warrantied to give off purer oxygen than a pregnant
woman could sniff from bottles.

Wading through creepers and mutant ficuses, I finally found the moss-lined
laundry hamper and threw in my work clothes. The fragrant Clean-U-Lichen had
already sani-scavenged and folded my exercise togs, which felt warm and
skin-supple when I drew them on. The organo-electric garment rippled across my
skin as if alive, seeming just as eager for a workout as I was.

I'd been through hell at the office. Traffic on the commuter-tube was miserable
and the smog index had been red-lining for a week. Termites had only been the
last straw.

"Let's go," I muttered. "I haven't killed anything all day."

Long Stick spotted a big old buck gazelle.

"It limps," my hunting partner said, rising from his haunches to point across a
hundred yards of dry savannah. "Earlier, it met a lion."

I rose from my stretching exercises to peer past a screen of sheltering
boulders, following Long Stick's gnarly arm. One animal stood apart from the
herd. Sniffing an unsteady breeze, the buck turned to show livid claw marks
along one flank. Clearly, this prey was a pushover compared to last Sunday's
pissed-off rhino. The virtual reality machine must have sensed I'd had a rough
day.

My hands stroked the spear, tracing its familiar nicks and knots. An illusion of
raw, archetypal power.

"The beaters are ready, Chief," my hunting partner said. I nodded.

"Let's get on with it."

Long Stick pursed his lips and mimicked the call of a bee-catcher bird. Moments
later, the animals snorted as a shift in the heavy air brought insinuations of
human scent. Another hundred yards beyond the herd, where the sparse pampas
faded into a hazy stand of acacia trees, I glimpsed the rest of our hunting
party, creeping forward.

My hunters. My tribe.

I was tempted to reach up and adjust the virtu-reality helmet, which fed this
artificial world to my eyes and ears . . . to zoom in on those distant human
images. Alas, except for Long Stick, I had never met any of the other hunters up
close. Good persona programs aren't cheap, and with a baby coming, there were
other things for Gaia and me to spend money on.

Yeah, like a cramroy termite hive! Resentment fed on surging adrenaline. Never
trust a gatherer. That was the hunters' creed. Love 'era, protect 'era, die for
them, but always remember, their priorities are different.

The beaters stood as one, shouting. The gazelles reared, wheeling the other way
-- toward us. Long Stick hissed. "Here they come!"

The Accu-Terrain floor thrummed beneath my feet to the charge of a hundred
hooves. Sensu-Surround earphones brought the stampede roar of panicky beasts
thundering toward us, wild-eyed with ardor to survive.

Clutching my spear in sweaty palms, I crouched as graceful animals vaulted
overhead, ribcages heaving.

Meanwhile, a faint, subsonic mantra recited. I am part of nature . . . one with
nature . . .

The young, and breeding females, we let flash by without harm. But then,
trailing and already foaming with fatigue, came the old buck, its leap leaden,
unsteady, and I knew the program really was taking it easy on me today.

Long Stick howled. I sprinted from cover, swiftly taking the lead. The
auto-treadmill's bumps and gullies matched whatever terrain the goggles showed
me, so my feet knew how to land and thrust off again. The body suit brushed my
skin with synthetic wind. Flared nostrils inhaled sweat, exhilaration, and for a
time I forgot I was in a tiny room on the eightieth floor of a suburban Chitown
con-apt, surrounded by fifty million neighbors.

I was deep in the past of my forebears, back in a time when men were few, and
therefore precious, magical.

Back when nature thrived . . . and included us.

Easy workout or no, I got up a good sweat before the beast was cornered against
a stand of jagged saw grass. The panting gazelle's black eye met mine with more
than resignation. In it I saw tales of past battles and matings. Of countless
struggles won, and finally lost. I couldn't have felt more sympathy if he'd been
real.

My throwing arm cranked and I thought -- Long ago, I'd have done this to feed my
wife and child.

That was then. As for here and now?

Well . . . this sure beats the hell out of racquetball.

Mass-produced con-apt housing lets twelve billion Earthlings live in minim
decency, at the cost of dwelling all our lives in boxes piled halfway to the
sky. Lotteries award scarce chances to visit mountains, the seashore. Meanwhile,
Virtuality keeps us sane within our hi-rise caves.

On my way to shower after working out, I saw that Gaia's private VR room was in
use. Impulsively, I tiptoed into the closet next door, feeling for the crack
between stacked room units, and pressed my eye close to the narrow chink of
light. Gaia squatted on her treadmill floor, shaped to mimic a patch of uneven
ground. Her body suit fit her pregnant form like a second skin, while helmet and
goggles made her resemble some kind of bug, or star alien. But I knew her
scenario, like mine, lay in the distant past. She made digging motions with a
phantom tool, invisible to me, held in her cupped hands. Then she reached down
to pluck another ghost item, her gloves simulating touch to match whatever root
or tuber it was that she saw through the goggles. Gala pantomimed brushing dirt
away from her find, then dropping it into a bag at her side.

Sometimes, eavesdropping like this, I'd feel a chill wondering how odd I must
look during workouts, leaping about, brandishing invisible spears and shouting
at my "hunters." No wonder most people keep VR so private.

Gaia tilted her head as if listening to somebody, then laughed aloud. "I know!
Didn't the two of them look funny? Coming home all proud with that skinny little
squirrel on a stick? Such great hunters! That didn't stop them from gobbling
half our carrots!"

Naturally, I couldn't see or hear Gaia's companions --presumably other women
gatherers in the same simulated tribe she had been visiting since years before
we met. She stopped again, listening, then turned around. "It's your baby,
Flower. That's okay, I'll take care of him." She laughed. "I need the practice."

I watched her gently pick up an invisible child. Her body suit tugged and
contracted, mimicking a wriggly weight in her arms. Awkwardly, Gala cooed at an
infant who dwelled only in a world of software, and her mind. I crept away to
take a shower, at once ashamed of spying and glad that I had.

Toweling my wet hair, I entered the bedroom to find the wall screen tuned to
Mother Earth Channel Fifty-Three -- a green-robed priestess reciting a sermon.

" . . . returning to more natural ways does not mean having to sacrifice nil
modern . . . ."

Gaia emerged from her closet wearing a bright cotton shift over her blossoming
figure, sorting through a cloth bag slung over one shoulder. "Where are you
going?" I tried asking, but the life-sized matron on the wall was doubly loud.

" . . . we should eat like our ancestors, who caught meat but twice a week or
so. All other food was gathered by skilled women . . . . "

I tugged Gaia's elbow, repeating my question. She startled, then smiled at me.
"NatuBirth class, Sweetheart. Lots to learn before I'm ready. Just two months
left, you know."

"But I thought . . . "

" . . . Fats and sweets were rare back then, hence our cravings. Now
self-discipline must take the place of scarcity -- "

I shouted. "Computer! Shut off that noise!"

The priestess's mouth moved silently. Gaia looked reproving.

"I don't like being left out," I complained.

Gaia stroked my face. "Oh Toms, don't be off-baud. We're just covering nest and
birthing methods, tonight. A man would be bored."

Hm. Maybe. Femismo says there are some things men can't understand. Quite a
shift from the way old-fashioned feminism preached sharing all life's duties. My
dad used to proudly tell of cutting the cord, the day I was born. I kind of
liked that idea, but now they call it unnatural. Birth has always been a female
ritual. That's what they say.

"You just stay home, be good, and . . . " Gaia pressed against me,
affectionately, her eyes lighting. "You had a good hunt, didn't you? I can tell.
It always leaves you frisky."

I pulled away. "Mph. Go to class, then. I'll be okay."

She tiptoed to kiss my chin. "Look by the console for a present . . . something
to show I haven't forgotten you." Gala blew another kiss from the front door,
and was gone.

I wandered over to the master house controller and picked up a brightly colored
program plaq, still tacky where Gaia must have peeled off a discount sticker
from the NatuLife Store. Something for the Hunter, the title read, and I
snorted. Right. Something to keep the man of the house distracted beating drums
with a bunch of make-believe comrades, while a wife's attention turns to serious
matters -- nesting and the continuity of life. The blyware gift might have been
meant as a loving gesture, but right then it made me feel superfluous, more left
out than ever.

Sliding the plaq into the console, I accidentally brushed the volume knob and
the booming voice of the priestess returned.

" . . . must face the fact that Earth's billions won't accept returning to
nature by scratching mud and sleeping on dirt floors. We must learn new ways,
both more natural and smarter . . . . "

I snickered at that. Funny how each generation thinks it knows what "smarter"
means.

LONG STICK greeted me with a sweeping bow, at once both sardonic and respectful.
"Welcome back, oh Great Chief."

"Yeah, yeah," I muttered at my simulated sidekick. "Okay, I'll bite. What's
different, this time?"

Everything seemed less real here in the living room, with my virtuality helmet
and body suit left hanging in the closet. The familiar, primeval forest of my
private world now cut off sharply where the vial-wall met the couch. Yet, I
could have sworn my ersatz companion seemed subtler, warmer, somehow.

"The flint-smiths are ready to show their wares, chief."

"The who . . . ?" I began. But Long Stick simply turned to begin striding down a
nearby path. The living room had no treadmill-floor, so I stood still, watching
Long Stick's buckskin-draped form plow past trees and boulders and down a series
of switchbacks. A rhythmic sound grew steadily louder--a tinny clatter of
brittle objects colliding and breaking. Finally, we reached a sandy streambed
where several figures could be seen sitting on logs, hammering stones together.

Oh, yes. Flint-smiths. NatuLife stocked countless "You-Are-There" programs in
all the ancient arts, from bronze casting to automobile design. With our shared
interest in the Neolithic, Gala had cleverly bought a stone age simulation the
computer could fit right into my private world, to help me pass an evening while
she trained for motherhood.

Okay, I sighed. Let's get on with it.

A youngster with a wispy beard noticed us, stopped hammering, and nudged the
others -- a weathered old man and a sturdy-looking fellow with one leg much
shorter than the other. The smiths rose and bowed respectfully. Naturally, these
wouldn't be full scale sim-personas, like Long Stick, but animated actors in a
limited scenario.

"We have worked those chert cores you traded from Seacliff Tribe, oh Chief," the
oldest one said, lisping through gaps in his teeth. "Would you like tO see?"

I shrugged. "Why not?"

He spread a fur and began laying out an assortment of neolithic cutlery,
glinting under ersatz sunshine. There were spearheads, axes, burins and scrapers
-- plus other tools I couldn't identify offhand -- each item the product of at
least a hundred strokes, skillfully cleaving native rock into shapes useful for
daily life. A prehistoric kitchen, armory and machine shop, all in one. The
smiths offered to let me feel an edge. It was disturbing to watch the computer
manifest an image of my own hand, holding an object I couldn't feel. I resolved
to try again later, replaying the scenario with body gloves on.

"Well, it's been interesting," I said after a while, feeling fatigued. "But I
think that's enough for n --"

A high shout broke in. Everyone looked past my shoulder, but the scene remained
obstinately riveted until a new figure entered view from the left. Shorter,
slimmer than the others, this one strode with a springy, elfin gait, clothed in
the tunic and leggings of a hunter. The newcomer carried a bundle of slender
wooden saplings the right size for fashioning spears. Only when these were
dumped with a clatter did I note with surprise that this hunter was female.

"Ho, Chief," she greeted me, acknowledging Long Stick with a nod.

My companion leaned over and muttered, "This is Ankle-of-a-Giraffe, daughter of
Antler and Pear Blossom. She is one of the beaters in the hunt."

"That's what I want to talk to you about," the young stone-ager said, planting
fists on her hips. She was lithe and a trifle lean for my tastes -- as well as
being smudged from head to toe-- but she made eye contact in a bold, provocative
way. "I'm sick of just beating, Great Chief. I want to be in on the kill. I want
to learn from you two."

The stone-smiths hissed surprise. Long Stick rambled. "Ankle! You forget
yourself!"

The girl bowed submissively, yet her eyes held fierce determination. She seemed
ready to speak again when I shouted.

"Freeze frame!"

All action halted, leaving the "tribesmen" locked in time. A blue jay hovered in
suspended flight across the gully while I wrestled with confusion. It wasn't the
idea of a female hunter . . . plenty of tribes allowed it, according to
tradition. But why complicate matters with such a player right now, just as the
simulation seemed about to end? What did it have to do with prehistoric
tool-making?

"Computer. This isn't just a packaged you-are-there, is it?"

"No it is not. These are fully autonomous persona programs, operating
stochastically in your private sire world."

So, Gaia had been generous after all! Long Stick was no longer my only,
full-scale companion. But how could she afford . . .

"In addition, core memory has been enhanced to allow up to five flexible
personae at any one time."

"Oh, I get it."

Gaia must have needed more memory for her own programs, the midwives and doulahs
and other helpers she'd need when the baby came. The expense was already
budgeted. No wonder she could throw in a few extra playmates for me, purchased
at discount. After wondering for a minute whether to feel hurt, pleased, or
amused . . . I finally decided it didn't really matter. I hesitated, then
decided.

"Computer, hold simulation for transfer to my rec room."

Minutes later, fully suited for virtuality, I held one of the tool-knappers' new
flint knives in my hands, each curve and serrated edge conveyed by subtle,
electrochem gloves. The stone-smiths seemed pleased by my admiration. It was a
good knife, of the finest obsidian, bound to an ivory handle carved with figures
of running horses. Despite not being real, it was the most splendid thing I had
ever owned.

The treadmill worked beneath my feet, mimicking movement as Long Stick and I
finally departed the neolithic factory, heading toward Lookout Point to observe
migratory herds of wildebeest and eland crossing the plain. Along the way, we
passed the young beater, Ankle, squatting by the river bank where she'd been
banished by Long Stick for impertinence. Tying stone points to spear-shafts,
tightening the leather thongs with her teeth, she looked up as we passed by,
unrepentant, a light of challenge in her eyes.

I paused, then turned to Long Stick. "We could use a scout to carry messages.
Next hunt, bring this one along."

My simulated friend returned one of his sharp looks, but nodded silently. Ankle
turned away, wisely hiding a jubilant grin.

I emerged from my primeval world to find Gaia already home from her class,
nestled in our small, darkened bedroom. I slipped between the sheets quietly,
but soon felt her hand upon my thigh. "I've been thinking about you," my wife
whispered, her breath warm on my ear.

Pregnancy doesn't exactly mean no sex. Doctors say it's all right if you're
careful.

In fact, it can be much better than all right. Gaia was very skilled.

The buffalo groaned, mired in muddy shallows with five spears in its flank. I
commanded no more thrown.

Ankle protested, waving her javelin. "Why not finish it off?"

"Because the Chief said no!" Long Stick snapped. But I gestured for patience.
With Ankle for an apprentice, I now appreciated the adage--You never really know
something til you teach it.

"Think. What happens if he falls where he stands?"

She eyed the panting beast. "He'll fall into the riv . . . Oh! We'd lose half
the carcass." Ankle nodded soberly. "So we try getting him ashore first?"

"Right. And quickly! We don't want him suffering needlessly."

Several tribesmen made pious gestures in agreement. Through ritual, hunters like
these used to appease the spirits of beasts they killed, which made me wonder --
would modem folk eat so much meat if they had to placate the ghost of each steer
or chicken? My time in a simulated stone age hasn't made a vegetarian of me, but
I better appreciate the fact that meat once lived.

Long Stick called for rope. Bearing coils of braided leather, we worked toward
the bull from three sides. The treadmill imitated slippery mud beneath my feet,
while the body suit tickled nerves so that I felt hip-deep in slimy water.
Electronically-stirred receptors in my nose "smelled" the creature's blood and
defiance, above the rank swamp stench. It was hard work, floundering toward our
prey. Harder and more varied than lifting weights in a gym, and more terrifying.
The buffalo shifted left and right, bellowing and threatening with its horns.

Everything had seemed more vivid since Gala bought that extra memory, including
this beast's hot zeal to survive. "Watch out!" Ankle cried as it lunged. I
swerved and felt a wall of fur and muscle glance off my shoulder, rushing
through space I'd just occupied. Teetering in the mud, I glimpsed a snaking
lasso chase the old bull, landing round its neck.

"Got him!" Long Stick cried.

"My turn!" called a higher voice. Ankle cast her lariat-- only to fall short as
the angry beast thrashed aside.

"Wait!" I cried when she plunged after it. Too late, I watched the girl vanish
beneath the frothy, scummy surface.

"Ankle!"

Suddenly, I was too busy dodging to worry about my young aide. Sharp horns
flashed viciously. While I knew the computer wouldn't kill me, other slipups in
the gym had left me bruised for weeks.

She's only a program, I told myself, backpedaling from a roaring shaggy face the
size of a small pickup. Programs can take care of themselves.

"Yip-yi-i-yip!"

The cry coincided with a sudden change in the creature's bellows. It whirled and
I blinked in astonishment. The young hunter, Ankle, had clambered on its back!
Dripping water and marsh reeds, she held tightly to its mane and slipped her
noose over the shaggy head, while the bull snorted, wild-eyed and convulsing.
Others joined her exultant shout as ropes pulled taut from three directions.

Resignation seemed to settle over the animal then, as it let itself be drawn
toward dry land. Two meters . . . three . . .

Suddenly, in one last, desperate heave, it reared. Ankle flew off, arms whirling
to splash near the bull's stomping hooves.

With a shout I dove toward her.

Or tried to. Today's virtuality tech can't fake buoyancy, so the machine
wouldn't cooperate. The body suit did let me flounder forward, though, evading
the thrashing horns while flailing underwater in search of my apprentice.
Frantic seconds passed . . . and finally I felt the touch of a slim arm! A small
hand closed vice-like round my wrist as I yanked back hard . . . just as the
buffalo pitched over, toppling with a mighty splash on the spot where Ankle had
lain.

We made it ashore downstream from where the tribe was already commencing the
frenetic ritual of butchery. In olden times, a kill like this came at best once
a month, so these hunters sang their joy to the spirits of water, earth and sky.
But the artful ceremony was wasted on me as I slogged uphill, feeling pressure
leave my cramping legs exactly like water slipping reluctantly aside. The weight
in my arms seemed all too real as I lowered Ankle to a patch of grass.

This was an awful lot of trouble to go to, just for a piece of software. I might
have rationalized that good persona programs are expensive, but the thought
didn't cross my mind as I hurriedly checked Ankle's breathing. Pale, mud-grimed
from crown to toe, she gave two sudden, wheezing coughs, then revealed twin
flashes of abalone blue as her eyes popped open. Ankle gasped a sudden, stricken
sob and threw both arms around my neck.

"Urk!" I answered. Never before had my exercise togs yanked me down so, into
such a flood of sensations. Pain lanced my palms from impacting pebbles.
Sunlight spread heat across my mud-splattered back. Then there was the press of
her warm body, clinging beneath mine, much more cushiony, in places, than I had
imagined.

Soon I realized Ankle no longer clung to me for comfort. She was moving
breathing in ways having little to do with reassurance. I grunted surprise for a
second time, and reached up to pry loose her arms. "Stop simulation!" I shouted.

My last glimpse, before yanking off the helmet, was of Ankle lying there, muddy
all over, wiry-strong and hunter-attired, yet suddenly utterly female, gazing at
me both worshipful and willing.

She was only software -- bits of illusion on a silicon chip. Besides, I barely
knew her.

She was already the second most desirable woman I had ever known.

Now get this, I love my wife. Always figured myself one of those lucky bastards
whose woman understands him, inside and out, and despite that thinks the world
of him.

So, I figured, there's got to be a mistake here!

Trembling I peeled off my sweaty body suit and stumbled into the shower,
wondering, How am I going to explain this to Gaia?

Then, while soaping myself, I thought, What's to explain? I didn't do anything!

Rinsing I pondered, And if I had? Would it've been adultery? Or an exotic form
of masturbation?

I recall how Morn blithely tolerated Dad's collection of mildly erotic
magazines, apparently quite unthreatened by his harmless, private fantasies. Nor
did Gaia ever seem to consider my electronic Playboy subscription a rival.
Sometimes she would dial it up herself . . . ."for the articles." Still, if a
certain amount of healthy, visually stimulated autoeroticism was okay, I also
knew it would hurt her terribly if I ever had a real-life affair.

So . . . what had nearly taken place in my VR gym? The experience seemed to fall
somewhere between bolting a co-ed and an encounter with an inflatable doll.

Too bad they never produced that sci-fi gimmick, a direct computer-mind
interlace. Then I might have dismissed any sim-adventure as something purely
mental. But so much of what we are and do is tied up in our bodies . . . the
nerves, hormones and muscles. To have a truly vivid experience, you must take
your meat along.

With flesh taking part, virtuality can mimic any surface. I've crawled across
grass and tide pools and steaming sands while stalking prey.

But simulating a woman . . . ?

"Hi-tech marches on, but this is ridiculous!" I laughed, drying under a blast of
warm air, then put on a terry cloth robe and went out to tell Gaia everything. I
had last seen my wife in the nursery, where she had been humming while sorting
things for the baby, and cheerfully wished me a "good hunt."

Gaia wasn't there, but I felt a warm glow just looking around the little room,
its walls decorated with hologram mobiles and floating planets. I had installed
most of the nursery equipment myself, including the bottom-baster, with its
simmering vat of Liquid Diaper. The flotation crib would be programmed to mimic
my wife's heartbeat and other rhythms, comforting baby's first weeks with
sensations familiar from the womb.

This was where my life was anchored, I thought. Not in some make-believe hunting
band that femismo psychologists thought every modem man required. My family. For
all its pollution, crowds and exhaustion, the real world was where you lived
real life.

"Gaia?" I asked, searching the living room. "You'll never guess what happened .
. . "

She wasn't there either. I tried the kitchen, throbbing with busy, scrabbling
sounds of captive insects. Still no sign of her.

Funny, I thought. She hadn't said anything about another NatuBirth class
tonight.

"Computer, did my wife leave a message where she was going?"

The control voice answered. "Your wife hasn't left the apartment. She is in her
Virtuality Room."

"Ah . . . of course. Her turn. Must have gone in while I showered."

I sat on the couch gingerly, still feeling tremors from this evening's hi-stress
workout. I picked up the remote control and scanned tonight's cable listings.
Besides the normal thousand channels of infotainment, there were amateur-rids,
pubforums, hobby and spec-interest lines, two-way chatshows, and"Uncle Fred"
showing slides of his blimp-ride to Everest. The usual stuff. I fell back on
dialing a good book from the library, and actually stared at the first page of
Robinson Crusoe for about ten minutes before pounding the cushion beside me.

"Hell."

I told myself I was getting up to fetch a drink . . . then to go to the can . .
. then to look in the closet for my tennis shoes . . . Maybe I'd go outside for
an old-fashioned walk . . . .

I found the sneakers where I'd left them, near the crack in the closet wall.
Leaning close, I heard soft sounds coming from the room next door -- my wife's
private sanctum.

They weren't sounds of conversation, but exertion, heavy breathing.

Well, gatherers also used to work hard, netting fish, cutting wild grain . . . .

I knew I was rationalizing as I brought my eye to the crack.

Wearing helmet and body suit, Gaia squatted much as the last time I had seen her
in this place, hands outstretched and down before her, as if grasping something.
Underneath, the treadmill-floor mimicked an oblong hummock which she straddled
while strenuously rocking back and forth. Whatever she was doing in her private
world, it apparently involved a lot of effort, for her head rocked back and I
heard her moan aloud.

I knew that sound. I looked again at the shape beneath her, and saw that it
recreated no patch of ground, no fallen log. Even without goggles for seeing,
earphones for hearing, or gloves for touching, I could tell the outlines of a
man.

I NEEDED THOSE sneakers, after all. I left at once, and took a walk along the
sky bridges lacing the gray metropolis at the forty story level, overlooking the
maze of transport tubes and vibrating machinery which keeps the city alive.
Looking up past the towering canyon walls of Chitown, I could see no stars, just
a hazy glow diffused by pollutant haze. Late at night, I should have been
grateful for the countless Public Safety cameras, peering from each lamp post.
But they only made me feel conspicuous, supervised. On the veldt, you don't fear
being victimized by a million strangers. Twenty thousand years ago there were no
strangers. All you needed was your tribe.

I ducked into a local bar, under a 4-D holoneon sign with one dimension burned
out. The beer was excellent, the atmosphere depressing. Other men sat nursing
drinks, scrupulously avoiding eye contact with those around them. A wire-o in
the comer kept dropping quarters into a stim-zap machine, then sticking his head
under the hood for direct jolts of electric pleasure. His sighs were sterile,
emotionless.

Gaia's had been throaty, lusty.

Now I knew where she had learned that provocative, swaying motion--the one she'd
used the last few times we made love. Apparently, she had a tutor, a good one.
One I would never meet, let alone get to punch in the face.

Fair is fair, I thought. Hadn't I already rationalized my own encounter with
sex-by-simulation, before finding out that Gaia was doing it first? If it fell
into the category of masturbation for me, and not infidelity, then why not for
her?

That's different! -- part of me replied. But hard as I tried, I couldn't see
how. My "rival" was a phantom, no threat in real terms. He could never
impregnate Gaia, or give her a disease, or boast of cuckolding me to my business
partners, or ever take her away from me.

What it really came down to was the mental image, provoking jealousy at a deep,
gut level. Jealousy based on ancient drives a civilized man should be able to
overcome.

I was no longer sure I wanted to be a civilized man.

No, I didn't get roaring drunk, or provoke a fight with the big guy two stools
down. I thought about it, but what the hell? By now I was much too skilled at
killing to trust myself in a friendly brawl, out in the real world. Anyway, my
neighbor also looked like he worked out. Maybe, for exercise, he took scalps
with Cochise, or rode with a VR Genghis Khan. Under our gray urban disguises, we
can all be dangerous mysteries.

I paid up and left.

Gaia was dozing on the couch when I got back, or pretending to be. She seemed
relieved to have me home, and I tried not to show my inner turmoil. I turned on
the TV wall and she, sensing it wiser, went to bed.

Half an hour later, I slipped into my body suit and re-entered my private world.

Weeks passed. Gala grew larger. We spoke little.

My consulting firm finally won the Taiko Tech account, worth millions. I rushed
home and celebrated with Ankle by first killing a lion, then making love by a
cool bend in the river. We lay together, listening to locusts and the wind in
the swaying branches, while a dry heat seemed to suck all the dank, fetid odors
of the office out of my skin. Tension at work had left knots up and down my
spine, which Ankle worked out with her strong hands.

She listened quietly to my recitation of setbacks and victories in the corporate
world, clearly understanding none of it. That didn't matter. My VR people knew
and accepted that their chief spent most of his time far away, in the Land of
Gods. In a way, Ankle was the perfect, uncritical sounding board.

If only it had been that simple dealing with the hanging, unspoken tension
between me and Gala. Ankle would have listened to that, too, but what was there
to say?

The whole thing was preposterous and my fault. Why should it bother me what my
wife did in fantasy play?

It did bother me. It was starting to split us apart.

"I want to show you something," Ankle announced, picking up her clothes and
evading my grasp. "Come," she urged. "Long Stick can send some boys for the
lion. There is something nearby you must see."

I shrugged into my tunic. "What is it?"

She only smiled and motioned for me to follow. Still wrestling to lace my
moccasins, I tried to keep up as she led me toward a forested rise. It lay in
the direction of "Camp," the fictitious home base I had never seen during all of
my workouts with small groups of hunters. It would have taken so much computing
power to process a full tribe that it simply never occurred to me to journey in
this direction.

We reached the top of the rise and soon picked up faint sounds . . . human
voices, talking and laughing. We approached stealthily, crawling the last few
meters to peer over a steep bluff. There we saw, a couple of hundred meters
downslope, a small gathering of people clustered around an oak tree. They were
using tall poles to bat away at an object high in the branches. Occasionally,
one of them dropped her pole and hopped about, swatting at the air while others
laughed.

Gatherers, I realized. Going after a beehive. This was my first glimpse of the
other half of my "tribe." Calmly, I noted that many were accompanied by children
. . . and that one of the unaccompanied ones was decidedly pregnant . . . .

My breath suddenly caught as I recognized the rotund, laughing figure.

All this time, Gaia and I had played in our own pretend neolithic worlds, and
never guessed they were different pans of the same tribe!

It hadn't started out that way. We had bought the original versions of our
programs separately, before we even met. But in retrospect it seemed an obvious
thing for the computer to do . . . to save memory space by pooling our
adventures in the same metaphorical landscape.

"It affects us," Ankle said.

"Who?"

"We. Your folk." She motioned toward the gatherers, slapped her own chest, and
waved toward the east, where the hunting parties roamed. "It hurts us."

"What hurts you?" I asked, perplexed, distracted.

"The break . . . the pain between you two."

I was too confused, too curious about this new turn of events to follow what she
was saying. I peered at the figures below, and saw two men among the women down
there, helping to steal honey. Just as some women could be hunters, certain
males might choose the rites and rhythms of gathering. Probably, one of them was
my rival, Gaia's synthetic paramour.

Suddenly it seemed important to get closer. But as I made ready, Ankle stopped
me.

"You cannot," she said.

"What do you mean?"

"Certain charms are needed. To unite us. Unite the tribe."

"Charms?"

She nodded. "From the Land of Gods."

After a pause. " . . . Oh, I get it."

She meant more memory, much more. Until recently, I had hunted with just one
companion, then ten or so. Joining the two simulated worlds, depicting several
score personified characters, would take more power than our house console
possessed.

But that was no problem! I had a big raise coming. I could go right out and buy
the chips on credit! My fist clenched in anticipation. By this time tomorrow,
I'd get a much closer look at the bastard who . . .

Suddenly, the laughter below broke under a single, warbling cry. One of the
women dropped her pole and doubled over in agony, clutching her swollen abdomen.

I didn't stop to think. With a bellow I came to my feet, running downhill toward
the petite form, writhing amid a cluster of anxious women. "Gala!" I cried,
frustrated that the ground grew tarry with each step. The gatherers, too, seemed
to blur around the edges as I neared, one heavy step at a time. The earth
trembled and Ankle clutched my arm.

"Not that way!" she screamed, cringing as I whirled in anger. "You must go!" She
slapped the side of her head, then pointed to mine.

Damn the realism of it all!

Cursing I tore off the helmet, gashing my cheek on the strap. The body suit
still formed a matrix of other-world sensations -- hot savannah wind and gritty
moccasins. But abruptly my eyes saw a tiny, off-white chamber, its coarse floor
of needles mimicking a steep hillside. Sense-conflict made me sway in confusion
as I dove for the door.

"I'm coming Gaia!" I cried, stumbling into the hallway in haste to reach my
wife.

They're making a big deal out of it. I've been interviewed on some of the lesser
zines. There's even talk of reviving childbirth classes for husbands. But it's
just silly, all the fuss. Any other man would've done the same. What matters is
that everything turned out all right.

Tommy junior thrives as his stim-crib cases him into the gaudy multi-world.
He'll grow up in Chitown, and on Mars, in mythic Greece and a neolithic clan.
He'll roam forests, to know what we've lost. As a teen, he'll live out fantasies
lads of my time only imagined. Still, even his generation will learn to tell
what's real. Reality is what still hurts when you take the suit off.

Gaia and I solved our problems once our tribes united. Each of us still plays
with personas now and then. Despite all the sudden yammerings of the neo-prudes
-- who could resist? Anyway, we always come home to each other, and that's what
counts. Virtuality is fun -- it's good to be the Chief -but nothing matches the
sweetness of her real skin, or the unpredictability of her real mind.

My blood pressure is low. My arteries are squeaky-clean and muscles wiry,
strong. I stay a little hungry, like my ancestors, and may live past a hundred.
In a cramped world of twelve billion souls, I can run for hours seeing no one
but gazelles, or a lonely hawk.

Lions know to give me a wide berth.

Let others be gods in their private realms. I'm content to be a man.

Give me time. I'm even learning to like termites.
