Here I am at the edge

 Genetic History You'd think by your late 60's you would know about your body, in my case that is not so, why? I have not given up the thoughts that my body has hidden genetic flaws, I doubt I will until I die, and even then I may have something hidden that only death can release. This is similar to the perrenal question, if a doctor knew you were going to die soon, would you wish to know? My answer has always been Yes.
