Life is dangerous: You could slip in the shower, get hit by a bus, mauled by a bear or drown in breasts (it happens, look it up). It always pays to be safe, and a life lived cautiously is a life lived long. For those of us who walk the cautious road and avoid the three lethal B's--buses, bears and breasts--wherever possible, life should be more or less safe. Right? Not in the slightest.
