In 20 or 30 years time, there's a good chance that medical science will have advanced to the point that you could live indefinitely, and at least some aspects of aging will have been reversed.
People are zombies, so they can't comprehend this. They will come out with some bull about aging being natural, it will cause overpopulation etc etc, even though any sane person knows that when these advances come about they will literally kill to have another decade on the planet in good health, let alone an extra 1,000 years.
Anyway, point is - save all you can, because at 50, you're either the last generation in history to die, or the first generation in history to live to be 1000. Those few extra bucks in the bank might make the difference. You can thank me later. Like in the year 3,000.
