Interesting theory (actually, hypothesis) about where one is born possibly affecting their heat/cold tolerance...what about where one has lived for most of their life? Actually in your case either one would make sense. I was born in the SF Bay Area at the end of December...it's in the 40s and 50s on average there at that time of year according to Wikipedia (assuming their info is accurate). Maybe that's part of why I like fall weather best, since here in MA we have a lot of fall temperatures in that range. I do OK with cold temps as long as I'm active and dressed properly (I have Raynaud's too, so that can be an annoyance if I'm not); heat isn't my thing. The one good thing about hot summer weather, IMO, is that it allows me to swim outside in natural bodies of water, which I like much better than being in a pool. I guess every season has its advantages; I do enjoy the variety of having four distinct seasons here and would miss that if I moved to a place that didn't have the same sort of variation.
