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

I loved the idea that biology was logical.

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.

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

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

In the early '90s, we discovered mutations that could double the normal life span of worms.

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