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

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

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

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

A big tree seemed even more beautiful to me when I imagined thousands of tiny photosynthesis machines inside every leaf. So I went to MIT and worked on bacteria because that's where people knew the most about these switches, how to control the genetics.

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.
