Ever wonder why humans have eyebrows? Surely, it goes beyond aesthetics. Nature did not provide it to man so he could make himself busy during idle moments.

The hairs prevent the sweat and rain from falling to our eyes, keeping it relatively dry and the vision clear. The same reason prevents eye irritation due to the salt content of sweat.
