Top 20 Questions of All Time

I like facts. So this list of the 20 greatest questions of all time was bound to grab my attention (though I think maybe it's a bit of an oversell to call them the greatest questions of all time). Anyway, some highlights: Humans are getting taller, people think OK comes from "oll korrect", fingers and toes get wrinkled in water because the waterproof coating gets rubbed off, some plants can live forever and chewing gum does not stay in your system for years.
