A recently-seeded article on medical advances in forestalling the effects of aging got me thinking. It seems like it is only a matter of time before science figures out how to drastically increase our lifespans. And yet -- as a society, we seem nowhere near achieving the state in which we can reasonably support our rapidly-aging populace at a standard of living to which we've all grown accustomed.
So I got to considering a thought-experiment, of sorts. Let's say that doctors invent a medicine that "cures" aging, so that for all intents and purposes you can take this drug and be immortal. The only problem: you must start taking it on or before your 18th birthday and (here is the kicker) it renders you completely sterile.
That is to say, you have a choice: either achieve immortality through science, or take a chance on "immortality" the old-fashioned way: by having children.
What would you do? What do you think most people would do?
