what do you find most surprising about humanity?

In the words of the Dalai Lama via Frank Weathers blog 

Man. Because he sacrifices his health in order to make money. Then he sacrifices his money to recuperate his health. And then he is so anxious about the future that he doesn’t enjoy the present; the result being he doesn’t live in the present or the future; he lives as if he’s never going to die, and then he dies having never really lived.
