My major concern for me personally would be if I actually trusted the procedure. As you know I have a big distrust of alopathic doctors & the billion dollar pharm industry. On the bigger picture, I would very much be concerned about people continuing to breed at a prodidious rate & then not having the decency to die. Were I the lord high dictator of the world, life extension treatments would only be made available to those with 0 or 1 living offspring, and the procedure would involve a mandatory sterilization procedure until the population was reduced to a billion or so.
