Even with seemingly simple things like eye color, you can't tell from my genetic code whether I have blue eyes or not. So it's naive to think that complex human behaviors, like risk-seeking, are driven by changes in one or two genes.

Preventative medicine has to be the direction we go in. For example, if colon cancer is detected early - because a person knew he had a genetic risk and was having frequent exams - the surgery is relatively inexpensive and average survival is far greater than 10 years.

It's very expensive to treat chronic diseases.
