My hope is that people will take the lessons of the past and apply them to the problems of tomorrow. Just be responsible in how you do it. There's also the reality that some genes that cause diseases in the individual are good for the population. The classic example is sickle cell anemia, where if you're a carrier, you have a protection against malaria. If you are living in Africa, this is good for the population, but bad for the individual who gets the disease.
Cystic fibrosis has a parallel in resistance to cholera in the population.
We also assume biomedical information is private, but you can't find something out about yourself without implicating other people. If you get tested, that can say something to the rest of your family. They may not want to know that information. And the insurance implications are another issue. A genetic test is more sophisticated than a heart test, for example.
