I agree that north India is the ultimate cow-belt and that is why it is the land of milk and honey. People are tall and disease free leading to a rapid increase in population. Alas, same can't be said about south! They have no cows anywhere in South. They have to drink their own fluids to obtain essential nutrients. Additionally, they have very high incidence of AIDS, perhaps due to loose Lungis?! Thus their population increase rates are low. And the ones who stay alive look so ugly. When I go abroad, and any South Indian approaches me, I pretend not to understand their language (which is true by the way). Who wants to associate with these international kallus?
