Aubrey de Grey: Seeker of immortality
Aubrey de Grey, British researcher on aging, claims he has drawn a roadmap to defeat biological aging. He provocatively proposes that the first human beings who will live to 1,000 years old have already been born.
Why you should listen to him:
A true maverick, Aubrey de Grey challenges the most basic assumption underlying the human condition -- that aging is inevitable. He argues instead that aging is a disease -- one that can be cured if it's approached as "an engineering problem." His plan calls for identifying all the components that cause human tissue to age, and designing remedies for each of them — forestalling disease and eventually pushing back death. He calls the approach Strategies for Engineered Negligible Senescence (SENS).
With his astonishingly long beard, wiry frame and penchant for bold and cutting proclamations,de Grey is a magnet for controversy. A computer scientist, self-taught biogerontologist and researcher, he has co-authored journal articles with some of the most respected scientists in the field.
But the scientific community doesn't know what to make of him. In July 2005, the MIT Technology Review challenged scientists to disprove de Grey's claims, offering a $20,000 prize (half the prize money was put up by de Grey's Methuselah Foundation) to any molecular biologist who could demonstrate that "SENS is so wrong that it is unworthy of learned debate."The challenge remains open; the judging panel includes TEDsters Craig Venter and Nathan Myhrvold. It seems that "SENS exists in a middle ground of yet-to-be-tested ideas that some people may find intriguing but which others are free to doubt," MIT's judges wrote. And while they "don't compel the assent of many knowledgeable scientists," they're also "not demonstrably wrong."
"Aubrey de Grey is a man of ideas, and he has set himself toward the goal of transforming the basis of what it means to be human."MIT Technology Review
Dean Ornish
Dean Ornish: Physician, author
Dean Ornish is a clinical professor at UCSF and founder of the Preventive Medicine Research Institute. He's a leading expert on fighting illness -- particularly heart disease with dietary and lifestyle changes.
Why you should listen to him:
Dr. Dean Ornish wants you to live longer, and have more fun while you're at it. He's one of the leading voices in the medical community promoting a balanced, holistic approach to health, and proving that it works. The author of Eat More, Weigh Less and several other best-selling books, Ornish is best known for his lifestyle-based approach to fighting heart disease.
His research at the Preventive Medicine Research Institute (the nonprofit he founded) clinically demonstrated that cardiovascular illnesses -- and, most recently prostate cancer -- can be treated and even reversed through diet and exercise. These findings (once thought to be physiologically implausible) have been widely chronicled in the US media, includingNewsweek, for which Ornish writes a column. The fifty-something physician, who's received many honors and awards, was chosen by LIFE Magazine as one of the most influential members of his generation. Among his many pursuits, Ornish is now working with food corporations to help stop America's obesity pandemic from spreading around the globe.
"Instead of trying to motivate [patients] with the 'fear of dying,' Ornish reframes the issue. He inspires a new vision of the 'joy of living' -- convincing them they can feel better, not just live longer." ~ Fast Company
