Age is the single largest risk factor for an enormous number of diseases. So if you can essentially postpone aging, then you can have beneficial effects on a whole wide range of disease.

It was like stepping on to an escalator; I could do anything. I was just made for science.

The idea that ageing was subject to control was completely unexpected.

You would think that UV just causes mutations, but it doesn't, you need a gene to be active for it.

Life's too short to not be around nice people.

I eat some fruit every day, but not too much and almost no processed food. I stay away from sweets, except 80 per cent chocolate.

In principle, if you understood the mechanisms of keeping things repaired, you could keep things going indefinitely.

Imagine that: If you could change one of the genes in an experiment, an aging gene, maybe you could slow down aging and extend lifespan.

I have always gotten a thrill, a kick, from learning new things.

Maybe one day we will be able to take a pill that keeps us young and healthy much longer. I believe in my heart that this will happen.

You could have two completely different careers if you could stay healthy to 90. How fascinating that would be.

She left, never to return. I planted a tree and a seed each time I thought of her. I grew a small forest and a large garden and had no one to give the orchids to.

The prison that exists in a man's mind is far more difficult to escape from than anything built with brick walls and steel doors. For it is the fear of freedom that holds you inside...

One accusation you can't throw at me is that I've always done my best.

I try to find out what the guy's strengths and weaknesses are. Like in boxing, I'd be a counter-puncher. Whatever he does well, I try to take advantage of what he doesn't do well.

Men are not our problem; it's what we are trying to get from them that messes us up. We use guys like mirrors to see if we're valuable.

Sometimes people need to be told to sit down and shut up.

They are specific places I have discovered here and there when I am on the road to take photos. I go especially to take photos.

I am convinced that our movement will be more demoralized and weakened by blind and uncritical admiration than by frank admission of past mistakes.

I do love poop. I can't help it. The heart wants what it wants. I enjoy being clever and pithy and political, but nothing's going to get me like dumb stuff.

We should desire neither the immortality nor the death of any human being, whoever he may be, with whom we have to do.
