There is no difference between saving lives and extending lives, because in both cases we are giving people the chance of more life.

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

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.

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.

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.

[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.

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.
