At one time, anthropologists tell us, humans had a protective coating of hair over their entire bodies that helped regulate body temperature and protect their skin from the sun.

That was back when, like other primates, we walked around naked, on all fours, and more of our skin was directly exposed to ultraviolet rays than it is today.

As we evolved to a standing position, we no longer needed hair everywhere, and experts at the Smithsonian Institute believe this was probably when we began to lose most of it.

Although we maintain the same number of hair follicles as apes, most of the hair on our bodies is comparatively fine in texture.

However, the man in the video used his hair as ‘rope swing’, which people won't believe if they don't see first hand.

A bizarre video from China shows a man hanging by his 1.3-metre-long hair and using it to swing from a tree, reports the feedytv.com.
