Because It's Important That's Why

I figured something out a while back and I just remembered and wanted to share it with you because... it's important, that's why.

So it has always seemed a bit arbitrary that humans only develop long hair in a few spots. Particularly on the head. Why is that? It's just weird. I mean, I appreciate not having to shave my whole body just so my clothes will fit right, but why do we have long hair on our head?

Well a few months back I shaved my head. Cue-ball short. When I did that I discovered something, my head temperature fluctuated a whole lot more than it had before. I know, duh right? But then I started thinking about it and realized that the top of our head is in fact different than the rest of our body. It's just shy of being an exoskeleton. So there is a very thin layer of flesh there to manage temperature changes. The rest of our bodies has inches for the most part.

So following my exhaustive scientific study, the top hair on our head is for temperature management.

The end.

Plus it looks nice.

Really the end.

And how else would they do shampoo commercials with the model flicking her hair as she burst from the sparkling ocean?

Really seriously the end.
