Speaking of pointless former president information. Someone on another message board I post at asked "what is the most number of former presidents to be alive at one time?"

I did the work and posted the answer but I might as well share the whole chart. I'll put it in a spoiler, though. The answer, by the way, is 5. Three separate times.
