I grew up in a lot of different climates. I've experienced temperatures from -45°F to +115°F, but those were the limits of the ranges, not the norms. I've been frostbitten four times, not counting my ears (most painful thing I've ever experienced) - and been chronically subclinically hyponatremic from sweating so much.

I don't doubt I'd have a lot harder time with the temperatures than I did when I was young, but here's the thing - even as a kid I could NEVER deal with damp. Never liked sledding or building snow people because I never found a way to keep my hands and feet from getting soaking wet. All my life I've much preferred a bracing 15°F, when it's dry of necessity, to 40°F when the damp goes right through me.

But I've never lived anywhere that the temperature didn't budge from the extreme for months.

Interesting that you mention Thailand, because one thing I'll always remember is what my first husband told me about coming home from a year-long deployment in Thailand, to Ohio in August. Eighty-five F and humid, and he was so freezing cold he spent his first couple of weeks home wrapped in blankets and wearing all the clothes he could. Then again, obviously he was young then too.

My dad really wanted to move full time back to North Dakota before he died. While I'm sad that he didn't get one last chance to walk the prairies, I really discouraged him from trying it. Forty below isn't the same thing for a very unhealthy 70-year-old as it was for a hale 35-year-old.
