I have always gotten a thrill, a kick, from learning new things.

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

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

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

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

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.

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

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.

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.

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

Just do it! First you make your habits, then your habits make you!

If you have time, you need a vision. If you have money you need a purpose.

In love one cannot be mediocre, nor can one sustain love without work. The choices in the past were not enough, and it was necessary to choose again.

Be sure your sin will find you out...Be sure.

The room has to be comfortable; the house has to look habitable.

If you let the world roll on the way it's rolling, you're voting for death. I'm not voting for death.

There is no advice that I can give you, you will just have to trust yourself that when the time comes, you'll make the right decision.

As the most social apes, we inhabit a mirror-world in which every important relationship, whether with spouse, friend or child, shapes the brain, which in turn shapes our relationships.

But just as nature abhors a vacuum -- so does the human heart.

I'm now so keenly aware that I have everything to prove and nothing to lose.
