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

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.

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

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.

I loved the idea that biology was logical.
