Nice

So I guess this really wise man decided that for his 50th birthday he was going to parachute out of his plane more times than anyone else in a 24 hr period. Can you guess how many times he jumped out? 640!!! I imagine it went something like this. About 18 hrs. into it, he was at 490 and thought, "well, if the rule still applies at such numbers, over the time I have left, I might just make 640." And he did.
