I think the question remains what happens when a certain mutation takes hold in the stem cell line? I'm guessing we'd need to a genetic map between your family members then (parents, siblings, etc)? Obviously radical life extension isn't a one solution problem, but I have to wonder how much will need to be done before we get something close to Aubrey de Grey's SENS program.
