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.

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

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.

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.

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.

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