What I'm after is not living to 1,000. I'm after letting people avoid death for as long as they want to.

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

Ageing is, simply and clearly, the accumulation of damage in the body. That's all that ageing is.

What I actually wanted to do with my life is make a difference to the world. That led me into science very quickly.

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.

It's not just about life, of course; it's about healthy life. Getting frail and miserable and dependent is no fun, whether or not dying may be fun.
