An Australian program featuring researchers Aubrey de Grey and David Sinclair: "It feels like science fiction, but it's actually true. And we're really at the cutting edge, it's a really exciting time in the field right now. ... There's no such thing as ageing gracefully. I don't meet people who want to get Alzheimer's disease, or who want to get cancer or arthritis or any of the other things that afflict the elderly. Ageing is bad for you, and we better just actually accept that. As far as I'm concerned, ageing is humanity's worst problem, by some serious distance. ... Now if you think that's an overstatement, consider this: world-wide, a hundred and fifty thousand people die each day, two-thirds of them from ageing. That means potentially one hundred thousand people could be saved every day with therapies that combat ageing. ... Ageing is simply and clearly, the accumulation of damage in the body. That's all that ageing is. What it's going to take is development of thoroughly comprehensive regenerative medicine for ageing. That means medicine which can repair the molecular and cellular damage that accumulates in our bodies throughout life, as side effects of our normal metabolic processes. ... We do not know what humanity of the future is going to want to do. If thirty or fifty years from now people don't have the problems that we thought they might have, but we didn't develop those therapies, so those people have to die anyway, after a long period of decrepitude and disease, then they're not going to be terribly happy are they? That's why we have a moral obligation to develop these technologies as soon as possible."
