Biomedical gerontologist Aubrey de Grey will be one of the scientists featured in a Barbara Walters special to be aired on April 1st. I can't imagine that this will be at all rigorous in its examination of longevity science, but the more who hear the message, the better: "From a potential breakthrough pill to controversial rejuvenation technologies, Walters reports on what the future may hold, as well as what one expert says is the only proven way to extend life. ... 'I think that within the next few decades, we have a pretty good chance of effectively defeating aging as a cause of death,' says [Dr. Aubrey de Grey], a respected and controversial expert on the biology of aging. But if the keys to living a long, healthy life are not found soon, some people will rely on [cryonics] - chemically preserving one's body at very low temperatures in hope of one day being brought back to life. ... Also, how close are we to using rejuvenation technology to regenerate body parts? ... 'someday, if you get into an auto accident, we'll just take a skin cell and grow you up a new kidney... cells could, in the future, replace almost any part of the body.'"
