Oh, one important part that I should have mentioned in my reply. Medical science is certainly different today than it was in the 60s. So, if you know there are certain problems you could develope, due to genetics, you get a good doctor, and put him in charge. Put yourself in your physican's hands, and then you have no worries. It is amazing what I have lived thru because of good medical care. This may be one very important reason to learn our family histories.
