And yet every time I get water down the wrong pipe - basically attempting to drown myself just trying to take in one of our most basic life-sustaining inputs - I realize that not only are we still basically monkeys but we haven't really evolved half as much as we think we have as a species. It's a miracle we live long enough to reproduce.
