Those of us with a torso that’s more like Chewbacca then Luke Skywalker have reasons to celebrate. Having body hair may make you self-conscious, but it can actually be quite useful in landing a date. Our bodies contain something called apocrine glands, which are located under the arms and near the genitals (two of the hairiest spots for most men). These glands produce an odorous chemical that acts to attract members of the opposite sex, like pheromones in animals. Body hair tends to trap those odors and amplify them, projecting the scent farther than it would otherwise go.
