I don't know whether it is important to study science at a young age, though current thinking emphasises the need.

My own field, the prevention of genetic disorders in babies, has been possible only because of humane work on animals.

Animal rights activists talk about cruelty and torture, some backing their assertions by publishing out-of-date photographs of "experiments" banned long ago. This is a misrepresentation. The work we do is performed with compassion, care, humanity and humility. I have never seen an animal suffer pain.

I went to school with butterflies of fear every day for years - from primary school onwards - not just worried about being bullied by classmates, but by teachers.

When I grew up, we didn't have a TV, and I think more families today have ambitions of getting out of their environment, such as sending their children to university.

You can't be judgmental about babies. They are all have different needs. I was left with an enduring hatred of cheese because it was forced down me when I was young.

Our aggression is a deep instinct which survives in all kinds of manifestations in modern man.
