Where I live, you can say "Howdy" and it just means hello. If you say "How ya doin'?" you will no doubt get a long long rundown of exactly how that person is doing, physically, financially, legally, and more. So if you don't want to hear it, don't ask.
There are a lot of things you could argue over, like air conditioning. Sure we can do without it, but when it's 100 degrees, it's hard to sleep, which makes it hard to work. But others would argue that one should just move to a cooler climate, which of course costs more for heat, in which case you should move to a warmer climate.
I'm 5'3" and always considered myself average. The linked article talks about how more height on a man helps him get the promotion or the girl... but those things are not just "functioning normally", they are competitions, in which someone else will lose out if you gain an edge.
