    I think it’s original purpose was to keep us warm, but with the advent of clothing it became more of a irritant.

    Now, I would give anything for it to fall out lol, I feel like Zangief.

      It is actually useful for detecting bugs crawling on your skin. Having them bump into hairs is way more effective than just giving them a free, smooth pass. Sure, we get lots of false positives, but in an evolutionary context where bug bites, venom, and diseases are significantly more dangerous, 100 false positives are worth avoiding the 1 false negative.
