I don’t think that’s it. It’s just what you’re used to. Here in Mexico I have met many people who don’t like ice cold beverages, and I suspect the lack of ice culture stems from the lack of potable water lines in houses thus ice makers aren’t common. You just grow up drinking water from the lukewarm delivered water barrel. Meanwhile I’m not sure I’ve met a single American who doesn’t like ice cold water (not to say you can’t find exceptional HNers). I think we’re just used to it.
