The urge to hold power is so incomprehensible to those of us who aren't possessed of it. I'm always at a loss as to why the likes of Mubarak and Gaddafi didn't just cash in their chips and head off for the luxury villas that surely could have been theirs; the only explanation can be that if you're the sort of person who wants to be in charge of things, that need never leaves you, and the more human concerns that would come first for the rest of us simply don't figure.
