“While on a hunting excursion, two adolescents saw and removed a dead armadillo. The armadillo’s blood got on his boots, which he wiped with his bare hands. This proved to be a near-fatal error, as the armadillo became infected with the bacteria that causes leprosy. He had to have surgery to remove damaged sections of his body.”

I also don't tail gate; look both ways when crossing a one way street; check that there aren't any cars coming if I'm about to walk past a big rain puddle, etcetera etcetera.
