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

If the aging process is controlled in a similar way in worms and humans, then we can use what we learn about worms to speed our study of higher organisms.

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

Generally, older people in their fifties, sixties, and seventies are running most countries and are CEOs of corporations. Which isn't to say there aren't entrepreneurs, but if the young were better in every respect, there'd be no reason for the old. Our life span reflects our particular life strategy.

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.

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

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