I see a definite business opportunity here, plus a way to end world poverty. All us (relatively) rich old people will "borrow" the children of impoverished foreigners, feed them up to good health, then bleed them long enough to recharge our aged selves, and ship them back home with a full belly and a fiver in their pockets. In short order, all the old people will have their youth back, and the poor people will have better health, full tums, and a little spending money, to boot. Everybody wins! Of course, we'll probably need to neuter the kids to prevent us from being overrun by foreigners, but that's a small price to pay. :-D
