Yeah, it's the old joke about futurists: When will humans become immortal? And every one of them gives an answer just short of their own expected demise.
The obligatory note: the true immortality is unattainable in principle without indestructibility (which is something that is hard to imagine even theoretically). Otherwise people will continue to die, en masse, from various unnatural causes. My guess as to the half-life of a human in the best of circumstances is just a couple of hundred years...
