I was really small and had a lot of health issues growing up. I mean, not compared to some people, certainly, but I had a number of full-body blood transfusions when I was kid.

My parents didn't have much money growing up, but they always had a budget for books.

I have scary eyes. I look like the guy in 'American History X,' yes. I remember coming home from school and asking my mum if I could get an eye transplant, and of course she declined.

I suppose my professional life can be split into writing books that all sound like infomercial products, most notably 'The 4-Hour Workweek,' and then tech investing.

In retrospect, I have devoted my scientific life mainly to the question to what extent infectious agents contribute to human cancer, trusting that this will contribute to novel modes of cancer prevention, diagnosis and, hopefully, later on, also to cancer therapy.

It's not a good idea to conceptualize a static relationship with long-standing policies, like health care.

Without truth, trust is lost. The ACA could not have been passed were it not for the repeated assertions, which proved to be false, that Americans who liked their health plans and their doctors could keep them.

I'm interested in the ideas that sound a little crazy, such as radical life extension, curing cancer, being able to create a simulation of the human brain and map every neuron.
