If amount consumed is any indication, that would have to be water – with coffee as a second runner up. And the rest of the pack is a muddled mess in which no one stands out, judging from the fact that the aforementioned are the only beverages that I drink on a daily basis. (Gin or beer are at most once a week beverages and average less than that, if this was meant to imply alcoholic drinks.)

Certainly, water is the only one that I: a.) can’t do without, and b.) could live a comfortable and healthy life drinking exclusively.
