We're back to the normal weather for this time of year in Nebraska, HOT. It's not too bad for me, since my basement stays fairly cool even when it's in the 90s and 100s outside. I just open the windows after it cools off at night. That doesn't work when it stays up in the 80s all night, so I do occasionally use a little A/C ... only a couple of times so far this year after it got up to 108 last week.
I usually don't mind either heat or cold while I'm awake. I like the variable weather in the plains of the Midwest, but when I'm asleep I need to stay warm. My body slows down a lot. My pulse gets down into the 20s and my body temperature get down to around to 96 or 97. I guess that's not too far from normal considering the amount that I exercise and the fact that I've been on a caloric restricted diet for over 30 years. I generally only eat 1500 to 1800 calories a day compared to the normal 2400 to 2700 required for my activity level. I'm fairly skinny, 6 ft - 140 lb, as a result, but I seem to also be very healthy. I save a lot on groceries too. --gk
