I'm the chief science officer of a foundation that works on the application of regenerative medicine to the problem of aging.

Theres no such thing as ageing gracefully. I dont meet people who want to get Alzheimers 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.

Most scientists will get serious media exposure about twice in their entire career. And they'll get that because they've actually done an experiment that was interesting.

I think it's reasonable to suppose that one could oscillate between being biologically 20 and biologically 25 indefinitely.

The right to choose to live or to die is the most fundamental right there is; conversely, the duty to give others that opportunity to the best of our ability is the most fundamental duty there is.

Theres nothing wrong with making the best of ones declining years, but what does annoy me is the fatalism. Now that were seriously in range of finding therapies that actually work against ageing, this apathy, of course, becomes an enormous part of the problem.

The aim is to postpone frailty, postpone degenerative disease, debilitation and so on and thereby shorten the period at the end of life, which is passed in a decrepit or disabled state, while extending life as a whole.
