For those of you planning to have babies in the future, I highly recommend harnessing the placebo effect by teaching your kids that the thing to do with a stubbed toe or bumped head or similar owie is to have a parent kiss it and blow on it. It actually seems to make them feel better from these little injuries there's nothing else to do about.
However, be aware that this may lead to having a preschooler who stops dead in the middle of a busy sidewalk to yell "My penis hurts!", yank down his pants, and demand loudly that you kiss it.
