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

I don't work on longevity, I work on keeping people healthy.

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.

My approach is to start from the straightforward principle that our body is a machine. A very complicated machine, but none the less a machine, and it can be subjected to maintenance and repair in the same way as a simple machine, like a car.

Ever since we invented fire and the wheel, we've been demonstrating both our ability and our inherent desire to fix things that we don't like about ourselves and our environment.

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

[Anti-aging therapies will] never be perfect, but we'll be able to fix the things that 200-year-olds die of before we have any 200-year-olds, and the same for 300 and 400 and so on.
