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

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.

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.

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 changing our world is playing God, it is just one more way in which God made us in His image.

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.
