One thing that's likely: How you look as you age is hereditary. Some of my family members, for example, look younger than their real age. And people have mistaken me for 30, even 25.

Ageing is very exciting. But if I didn't work on ageing, I'd want to work on the brain. There are really cool techniques you can use now. And bioinformatics. The methods you can use for comparing large data sets - that's so powerful.
