In loving, living memory, John Melançon 1928 – 2007
I suppose there's an evolutionary advantage to liking cold water and hot food – in both cases, more likely to be fresh (at least with the latter in case of meat, but I'm a vegan so don't take my word for any of that).
And stick to cold water. Municipal tap water in the U.S. is of good quality, but getting hot water from the tap can leach lead and other good stuff from your own home or building's pipes.
