Aubrey de Grey, 44 Going on 1,000, Wants Out of Old Age
By Joel Garreau
Washington Post Staff Writer
Aubrey de Grey may be wrong but, evidence suggests, he's not nuts.
This is a no small assertion. De Grey argues that some people alive
today will live in a robust and youthful fashion for 1,000 years.
In 2005, an authoritative publication offered $20,000 to any
molecular biologist who could demonstrate that de Grey's plan for
treating aging as a disease -- and curing it -- was "so wrong that
it was unworthy of learned debate."
Now mere mortals -- who may wish to be significantly less mortal --
can judge whether de Grey's proposals are "science or fantasy," as
the magazine put it. De Grey's much-awaited "Ending Aging: The
Rejuvenation Breakthroughs That Could Reverse Human Aging in Our
Lifetime" has just been published.
The judges were formidable for that MIT Technology Review challenge
prize. They included Rodney Brooks, then director of MIT's Computer
Science and Artificial Intelligence Laboratory; Nathan Myhrvold,
former chief technology officer of Microsoft; and J. Craig Venter,
who shares credit for first sequencing the human genome.
In the end, they decided no scientist had succeeded in blowing de
Grey out of the water. "At issue is the conflict between the
scientific process and the ambiguous status of ideas that have not
yet been subjected to that process," Myhrvold wrote for the judges.
Well yes, that. Plus the question that has tantalized humans
forever. What if the only certainty is taxes?
* * *
Dodging death has long been a dream.
Our earliest recorded legend is that of Gilgamesh, who finds and
loses the secret of immortality.
The Greek goddess Eos prevails on Zeus to allow her human lover
Tithonus to live eternally, forgetting, unfortunately, to ask that
he also not become aged and frail. He winds up such a dried husk
she turns him into a grasshopper.
In "It Ain't Necessarily So," Ira Gershwin writes:
Methus'lah lived nine hundred years
Methus'lah lived nine hundred years
But who calls dat livin' when no gal'll give in
To no man what's nine hundred years.
Aubrey David Nicholas Jasper de Grey, 44, recently of Britain's
Cambridge University, advocates not myth but "strategies for
engineering negligible senescence," or SENS. It means curing aging.
With adequate funding, de Grey thinks scientists may, within a
decade, triple the remaining life span of late-middle-age mice. The
day this announcement is made, he believes, the news will hit
people like a brick as they realize that their cells could be next.
He speculates people will start abandoning risky jobs, such as
being police officers, or soldiers.
De Grey's looks are almost as striking as his ambitions.
His slightly graying chestnut hair is swept back into a ponytail.
His russet beard falls to his belly. His mustache -- as long as a
hand -- would have been the envy of Salvador Dali. When he talks
about people soon putting a higher premium on health than wealth,
he twirls the ends of his mustache back behind his ears, murmuring,
"So many women, so much time."
A little over six feet tall and lean -- he weighs 147 pounds, the
same as in his teenage years -- de Grey shows up in a denim work
shirt open to the sternum, ripped jeans and scuffed sneakers,
looking for all the world like a denizen of Silicon Valley.
Not far from the mark. De Grey's original academic field is
computer science and artificial intelligence. He has become the
darling of some Silicon Valley entrepreneurs who think changing the
world is all in a day's work. Peter Thiel, the co-founder and
former CEO of PayPal -- who sold it in 2002 for $1.5 billion,
pocketing $55 million himself -- has dropped $3.5 million on de
Grey's Methuselah Foundation.
"I thought he had this rare combination -- a serious thinker who
had enough courage to break with the crowd," Thiel says. "A lot of
people who are not conventional are not serious. But the real
breakthroughs in science are made by serious thinkers who are
willing to work on research areas that people think are too
controversial or too implausible."
At midday in George Washington University's Kogan Plaza off H
Street NW, you are surrounded by firm, young flesh. Muscular young
men saunter by in sandals, T-shirts and cargo shorts. Young blond
women sport clingy, sleeveless tops, oversize sunglasses and the
astounding array of subtle variations available in flip-flops and
painted toenails.
Is this the future? you ask de Grey.
"Yes, it is precisely the future," he says. "Except without people
who look as old as you and me."
"Of course the world will be completely different in all manner of
ways," de Grey says of the next few decades. His speech is thick,
fast and mellifluous, with a quality British accent.
"If we want to hit the high points, number one is, there will not
be any frail elderly people. Which means we won't be spending all
this unbelievable amount of money keeping all those frail elderly
people alive for like one extra year the way we do at the moment.
That money will be available to spend on important things like,
well, obviously, providing the health care to keep us that way, but
that won't be anything like so expensive. Secondly, just doing the
things we can't afford now, giving people proper education and not
just when they're kids, but also proper adult education and
retraining and so on.
"Another thing that's going to have to change completely is
retirement. For the moment, when you retire, you retire forever.
We're sorry for old people because they're going downhill. There
will be no real moral or sociological requirement to do that. Sure,
there is going to be a need for Social Security as a safety net
just as there is now. But retirement will be a periodic thing.
You'll be a journalist for 40 years or whatever and then you'll be
sick of it and you'll retire on your savings or on a state pension,
depending on what the system is. So after 20 years, golf will have
lost its novelty value, and you'll want to do something else with
your life. You'll get more retraining and education, and go and be
a rock star for 40 years, and then retire again and so on."
The mind reels. Will we want to be married to the same person for a
thousand years? Will we need religion anymore? Will the planet fill
to overflowing?
But first -- why are these questions coming up now? And why are we
listening to answers from Aubrey de Grey?
Appalled at the Carnage
De Grey became the archenemy of aging in two steps.
"The first stage happened when I was probably 8 or 9 years old. My
mother wanted me to practice the piano, and I would resist it.
"She'd already somehow brought me up to be very analytical and
introspective. So I realized it was very straightforward. The best
possible outcome of my putting in this enormous time at the piano
is that I would become a good pianist. That wasn't good enough. I
would make a minimal difference in the world, because there were
plenty of other very good pianists already. Well, that won't do.
What I actually wanted to do with my life is make a difference to
the world. That led me into science very quickly."
In his teens he heard the siren song of the the first British
microcomputers, the Sinclairs and Acorns, and never looked back.
Computer science filled his undergraduate years at Cambridge and
became the field in which he spent more than a decade.
The second stage started when he was 26. De Grey fell in love with
and married a geneticist, Adelaide Carpenter, who is 19 years his
senior.
He learned a lot of biology over the dinner table, he says, and
gradually became driven by the notion that "aging is responsible
for two-thirds of all death -- now that means worldwide 100,000
people every single day -- and in the industrialized world, it is
something like 90 percent."
The further he got into Carpenter's world and that of her senior
colleagues, the more incensed he became that biologists and
gerontologists just accept this carnage.
"I was appalled. Utterly appalled. I began to realize the profound
difference of motivation and mind-set between scientists on the one
hand and technologists and engineers on the other hand."
In his world of information technology, the norm is making the
world new. Try something and if it doesn't work, try something
else. Science doesn't pave the way for engineering, it's the other
way around. Intel figures out a way to make wires only a few
molecules thick. Why the circuits function is at best of passing
interest -- as long as they do. Science can take years if not
decades to catch up with an adequate explanation of the device's
quantum mechanics. It is the final triumph of Edison over Einstein.
The idea of bringing pragmatism to biology made de Grey think "I
might be able to make a contribution. I became very aware by this
time that biology was critically short of synthesizers -- people
who brought ideas together from disparate fields who came up with
new ideas for experimentalists to do." So he got his PhD in biology
from Cambridge and started scattering ideas like viruses.
Aging consists of seven critical kinds of damage, according to de
Grey. For example, unwholesome goo accumulates in our cells. Our
bodies have not evolved means quickly to clean up "intracellular
aggregates such as lipofuscin." However, outside our bodies,
microorganisms have eagerly and rapidly evolved to turn this toxic
waste into compost. (De Grey made this connection because he knew
two things: Lipofuscin is fluorescent and graveyards don't glow in
the dark.)
By taking soil samples from an ancient mass grave, de Grey's
colleagues in short order found the bacteria that digest lipofuscin
as easily as enzymes in our stomachs digest a steak. The trick now
is getting those lipofuscin-digesting enzymes into our bodies. That
has not yet been done. But, de Grey says, comparable fundamental
biotechnology is already in clinical use fighting diseases such as
Tay-Sachs. So he sees it as merely an engineering problem.
Examples like this make up the 262 pages at the center of "Ending
Aging."
"It's a repair and maintenance approach to extending the functional
life span of a human body," de Grey says. "It's just like
maintaining the functional life span of a classic car, or a house.
We know -- because people do it -- that there is no limit to how
long you can do that. Once you have a sufficiently comprehensive
panel of interventions to get rid of damage and maintain these
things, then, they can last indefinitely. The only reason we don't
see that in the human body now is that the panel of interventions
we have available to us today is not sufficiently comprehensive."
By 2005, his ideas had attracted enough attention as to no longer
be merely controversial. De Grey was being pilloried as a
full-blown heretic.
"The idea that a research programme organized around the SENS
agenda will not only retard ageing, but also reverse it -- creating
young people from old ones and do so within our lifetime, is so far
from plausible that it commands no respect at all within the
informed scientific community," wrote 28 biogerontologists in the
journal of the European Molecular Biology Organization. Their
recommendation: more of the patient, basic scientific research that
is their stock in trade.
"Each idea that we decide to pursue will cost years of work and a
great deal of money, so we spend a lot of time -- at meetings,
seminars and in the library -- trying to search for and weigh
alternatives, and looking for loopholes in our chain of arguments
before they are pointed out to us either by peer reviewers or
experimental results.
"Presented by an articulate, witty and colourful proponent, a
flashy research agenda might catch the eye of a journalist or
meeting organizer who is hunting for attention, publicity and an
audience; however, the SENS agenda is easily recognized as a
pretence by those with scientific experience.
"Why not simply debate with de Grey and let the most convincing
arguments win? It is . . . our opinion that pretending that such a
collection of ill-founded speculations is a useful topic for
debate, let alone a serious guide to research planning, does more
harm than good both for science and for society."
The resulting uproar was followed by the put-up-or-shut-up
smack-down in MIT Technology Review. The upshot was intriguing.
"In our judgment none of the 'refutations' succeeded," Myhrvold,
one of the judges, writes in an e-mail.
"It was a bit ironic because they were mostly the work of
established scientists in mainstream gerontology who sought to
brand de Grey as 'unscientific' -- yet the supposed refutations
were themselves quite unscientific.
"The 'refutations' were either ad hominem attacks on de Grey, or
arguments that his ideas would never work (which might be right,
but that is what experiments are for), or arguments that portions
of de Grey's work rested on other people's ideas. None of these
refute the possibility that he is at least partially correct.
"This is not to say that the MIT group endorsed de Grey," Myhrvold
emphasizes, "or thinks he has proven his case. He hasn't, but
admits that upfront. All of science rests on ideas that were either
unproven hypotheses or crazy speculations at one point. . . . The
sad reality is that most crazy speculations fail. . . . We do not
know today how to be forever young for 1,000 years, and I am deeply
skeptical that we will figure it out in time for me!"
No Point in Being Miserable
Off the J Street food court at GWU, there is a cafe so
metabolically correct that it features not only a vegan service
bar, but, separately, a vegetarian service bar, which is not to be
confused with the salad bar.
Seems like a good place for lunch with a man intent on immortality.
Not so much.
"I'm getting damn thirsty," de Grey announces.
What appeals to him is the Froggy Bottom Pub on Pennsylvania
Avenue. "I like good beer, but I'm not really a snob about beer.
I'm perfectly happy to drink Sam Adams, if that's what they have."
Aubrey de Grey is not interested in spending his next centuries
miserable. He cheerfully chows down on french fries, heavily
crusted deep-fried chicken and two dark beers.
So beyond the question of whether immortality is feasible, is it a
good idea? For every Woody Allen who says, "I don't want to achieve
immortality through my work; I want to achieve it through not
dying," isn't there a Ralph Waldo Emerson who asks, "What would be
the use of immortality to a person who cannot use well a half an
hour?"
Why is it, when you bring up the idea of living forever -- even if
robust and healthy, not drooling on your shoes -- some people just
recoil viscerally?
"It's probably the majority that recoils viscerally," de Grey says.
"It's what I call the pro-aging trance.
"Since the beginning of civilization, we have been aware that aging
is ghastly and that aging is utterly inevitable. . . . So we have
two choices. Either we spend our lives being preoccupied by this
ghastly future or we find some way to get on with our miserably
short lives and make the best of it.
"If we do that second thing, which is obviously the right thing to
do, then it doesn't matter how irrational that rationalization
might be. . . . It could be, well, we're all going to go to heaven.
Or it could be, we're going to have overpopulation. Or it could be,
it will be boring. Or, dictators will live forever.
"It doesn't matter what the answers are. It's so important for them
to maintain their belief that aging is actually not such a bad
thing, that they completely suspend any normal rational sense of
proportion."
But if people don't die, won't we indeed fill the planet shoulder
to shoulder?
"The birthrate is going to have to go down by an order of
magnitude," de Grey acknowledges. "But even if that is going to be
a severe problem, the question is not, do problems exist? The
question is, are they serious enough to outweigh the benefits of
saving 100,000 lives a day? That's the fundamental question. If you
haven't got an argument that says that it's that serious that we
shouldn't save 30 [bleeping] World Trade Centers every [bleeping]
day, don't waste my time. It's a sense of proportion thing."
So de Grey soldiers on, not that it is anywhere written that
anything he advocates will work. His approach, however, does have
echoes in history.
On Oct. 9, 1903, the New York Times wrote:
"The flying machine which will really fly might be evolved by the
combined and continuous efforts of mathematicians and mechanicians
in from one million to ten million years."
On the same day, on Kill Devil Hill, N.C., in his diary, a bicycle
mechanic named Orville Wright wrote:
"We unpacked rest of goods for new machine."
