Everyone knows that beards are dope as hell, despite what's currently happening with Kit Harington's face. Some proper scruff provides a touch of organized chaos, and can dramatically elevate your look with only minimal input. All you have to do is stop shaving, really. But with Memorial Day in the rearview and summer hot on the horizon, chances are that soon you might find yourself reaching instinctively for a razor. And we understand why: heat, humidity, and an increased likelihood of exposed skin help reinforce the idea that having a beard between June and September would be rather uncomfortable.
The epic history and legend of the beard goes back a long, long way. In prehistoric times, scientists believe that men grew long beards for three main reasons. First, for warmth. The beard provides the face with protection from the elements, and a natural shield from the more delicate parts of the face around the mouth and lips.
These guys make a ritual out of shaving every summer out of fear of the heat. It makes sense. I mean, when you think about it the idea of having a massive patch of fur covering half of your face would sound like a great way to make the most out of the summer heat.
A simple answer to your question is that all mammals have hair. It is one of the criteria that scientists use to classify mammals to separate them from other vertebrate animals such as birds and reptiles. This means that even whales, elephants and dolphins have body hair!
