If you wanted to dissect the structure of living cells, genetic analysis was an extremely powerful method, so my interest turned to that.
My ambitions were already very clearly fixed by the time I was 6 or 7.
I wish I had a talent for dropping things as well as taking on new ones. It gets to be quite a clutter after a while.
By the time I was 12 or 13, I was studying biochemistry textbooks.
If lifespan jumps by 30 or 40 years, that has enormous implications.
I get curious about new things. My real strength is going into a field that has not been investigated before, and finding new approaches to it.
