There have been experiments that show getting 'young' blood transfused has a rejuvinating effect Indeed, those links I supplied in my original comment were to that effect. moral issues - is a clone of you sentient Definitely an interesting issue, but one I tried to head off by writing "brainless clone" in my original comment. I guess there would be moral questions about how one could create a clone without a brain. The easiest would be to interfere with the fetus to cause brain death, which does introduce the moral quandary. Personally, I would say that a clone with its brain intact should be considered it's own person. A clone would essentially be your identical twin, just a different age. It would not be ok to kill off your twin, even if they have a goatee :-)
