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.

No matter what happens to us in life, we tend to think of it as 'good' or 'bad.' And most of us tend to use the 'bad' label three to 10 times as often as the 'good' label. And when we say something is bad, the odds grow overwhelming that we will experience it as such.

We are not seeking... and looking for war with any nations. We are seeking peace and stability among all the nations in the region.

This country has a proud history of opening its doors to generations of people fleeing personal persecution, civil unrest and war.

But I do like to have peace and quiet for a good hour.
