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.

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.

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.

Basically, the body does have a vast amount of inbuilt anti-ageing machinery; it's just not 100% comprehensive, so it allows a small number of different types of molecular and cellular damage to happen and accumulate.

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