I wish I had long hair where it grew to huge length.
I have rather long hair right now.  I like it but it becomes a hassle to manage.  What inspires you to have long hair?
The fact that I cant grow it. Apparently only a few species like humans, horses, and orangutans have long hair
That's interesting! I never thought of that but it's true. And I assume we're the only species that dye our hair.
I think so. Hair is just to protect our scalp from the suns radiation.
That makes sense. But as humans we of course took something practical and made it a source of expression as well.
True. Good thing we still have it. We lost our fur about 3 million years ago.
I wonder why we kept our hair but lost our fur.  Any ideas?
Natural selection. Hair is needed to protect us from the sun. No fur makes us run faster which we needed back then to hunt.
