" I’m Jennifer Couzin-Frankel, a reporter for Science. I’m delighted that we’re joined today by two longtime experts in this fascinating field, Jay Olshansky, a professor at the University of Illinois, Chicago, and Aubrey de Grey, a biomedical gerontologist based in Cambridge, U.K., and chief science officer of SENS Foundation, a California-based charity that is trying to combat the aging process."
Dr. Aubrey de Grey is the brilliant and controversial scientist who is one of the major figures encouraging science in the direction of "longevity escape velocity," the point at which healthy life extension of, say, one year of extra living is achieved in less than a year. That would mean that while nobody would instantly become immortal, still, your chances of hale survival would increase every year, rather than diminishing. We dedicated our novel Post Mortal Syndrome to Aubrey, even though our story is a thriller, a sort of dramatized parable rather than a direct expression of his own approach to longevity.
Professor Olshansky is a demographer who finds some of Aubrey's optimistic expectations and analysis unlikely and even reckless. But it's a mark of the way the once-ridiculed topic is being reconsidered these days that he is happy to share an interview platform with Aubrey, and to advance his own more modest model of health extension under the rubric The Longevity Dividend.
Here are some extracts from the chat, where both men give brief answers to questions from the listening audience.
Olshansky: Although my friend Aubrey and I disagree on many things, most of what we disagree on is entirely irrelevant. It's what we agree on that is far more important, and that is, the time has arrived to take an entirely new look at aging. We now spend an enormous sum of money attacking the diseases that arise at later ages, but comparatively little on the underlying risk factor for most of what goes wrong with us as we grow older -- aging. I hope this conversation helps us all move in this direction, but you can certainly expect much more for my colleagues and I in the near term on an extension of The Longevity Dividend.
