If you think about evolution, sleep, at some time, was a dangerous undertaking. You lie down in your cave or shelter, and along comes a predator and has you for dinner. Many creatures do not sleep or sleep while standing so they can escape from dangerous situations.

If the death of Osama Bin Laden brings any peace to those who lost loved ones on that awful day in September 2001, that is a great thing. It is more likely, however, just a painful reminder of what was lost.
