I turned 65 last year, and each year I get more and more interested in human health. For most people it happens around age 50, but I've always been a slow learner. It's critical in terms of the cost of health care.

I've had a very unusual background in science - not the usual route of planning on being a scientist from age 3. I think my story shows that success is more about personal motivation and determination than it is about where you were born or what your economic status was.

In the past, geneticists have looked at so-called disease genes, but a lot of people have changes in their genes and don't get these diseases. There have to be other parts of physiology and genetics that compensate.

My early years were hardly a model of focus, discipline, and direction. No one who met me as a teenager could have imagined my going into research and making important discoveries. No one could have predicted the arc of my career.

When you act in a film, you're inevitably surrounded by people you didn't choose, right down to the set painter. I like being able to pick the family I'm waking up to in the morning that's going to make this group effort to tell a story that applies to what's interesting to me at that stage in my life.

The imperfections in my family made me learn to deal with things on my own and solve problems for myself.

I always wanted to be a chef. Flavors and food were always of interest to me, but it was how those things brought friends and family together to celebrate not only the special occasions but everyday life. It has been a blessing that I have been able to pursue a career that creates a product that brings people together.

Parents can only do what they think is best, with the experience they have. The learning curve for every parent is that there's a limit to how much they can shield children from.
