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.

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.

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.

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

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