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.

In the eye, there is a type of junk that accumulates in the back of the retina that eventually causes us to go blind. It's called age-related macular degeneration.

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

The biggest handicap in research is an ability to think outside the box. The handicap is being encumbered by all the conventional wisdom in a given field.

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.

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.
