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.

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.

I dont often meet people who want to suffer cardiovascular disease or whatever, and we get those things as a result of the lifelong accumulation of various types of molecular and cellular damage.

Accept the difficulty of what you cannot yet change. But do not accept the impossibility of ever changing it.

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

The scientific method actually correctly uses the most direct evidence as the most reliable, because that's the way you are least likely to get led astray into dead ends and to misunderstand your data.

If you look at winners of the Nobel Prize in biology, you'll find a fair smattering of people who don't know how to work a pipette.
