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

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

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

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

I loved the idea that biology was logical.
