Once in my twenties, I worked in an office of women in their forties and fifties. My teeth would be chattering while they all sat there fanning themselves.
I vowed that would never happen to me. Well. so much for that vow. :-)
I have to admit, I’ve never had that problem. All my life I’ve gotten hot more easily than everyone else around. Reaching that certain age (which happened early thanks to operation) just made it worse. I could honestly sit in a tub of ice in summer and love it, I take cold showers in summer as it is, and I started getting in the pool and loving it back in April! All I eat in summer is lime and pineapple popsicles, it’s too hot to eat real food, and the popsicles lower my core temperature for a little while.
