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.

The hope is that if we can increase youthfulness, we can postpone age-related diseases.

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.

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.

I loved the idea that biology was logical.

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

If I were a worm, I would rather be the long-lived mutant than the normal worm, that's for sure.
