I hope I've lived a life of science whose style will encourage younger people.

I certainly saw science as a kind of calling, and one with as much legitimacy as a religious calling.

If lifespan jumps by 30 or 40 years, that has enormous implications.

When I was in high school, I became interested in cytochemistry: chemical analysis under the microscope, and trying to understand the composition of cells.

I'm not easily inhibited by the fact that I don't know something about a subject. It doesn't stop me from dabbling in it.

I don't believe anybody can really grasp everything that's even in one textbook.

I believe I am a person with unusual talents. I think I'd be a liar or stupid if I were to deny that.
