Why do most people prefer to drink cold water?

Some areas of the world where there is little refrigeration they drink everything at room temp. I lived in one of those places and learned to like it. When I returned to the US, it was often hard to find unrefrigerated drinks in a resturant or bar so I gradually changed back to cold.

I thomk the answer is, we develop tastes from what we're used to and it becomes a habit.
