THE GREATEST UNANSWERED QUESTIONS IN THE HISTORY OF MAN KIND!

Why are all Kerala men (and unfortunately few women too) bearing big moustaches?
Are Kerala babies born already provided with big moustaches?

Not even science could come up with an appropriate answer to this question.

During a 4 hours long jeep trip to Cochin airport to Changanacherry I did count thousands of men on the road and every single one of them was having a moustache on his face, some had black, grey for the older men but everyone of them was having hair on his face (and I repeat unfortunately also some women too).

Why?
