I saw what happened when a dictator was allowed to take over a piece of a country and the country went down the tubes. And I saw the opposite during the war when America joined the fight.

I have a Ph.D. in cell biology. And that's really manual labor. I mean experimental science you do it with your hands. So it's very different. You're out there in a lab cleaning test tubes and it just wasn't that fascinating.

So someday in the near future hopefully rather than having a foot or a leg amputated we'll just give you an injection of the cells and restore the blood flow. We've also created entire tubes of red blood cells from scratch in the laboratory. So there are a lot of exciting things in the pipeline.

ER was one of my favourites. I played a car accident victim who has leukemia. I got to wear a neck brace and nose tubes for the two days I worked.
