OMG, I was just thinking this same thing today. Im alittle opposite tho. When it was cooler out, I was limp and had drop foot on my right foot. Now that its over 90, my muscles have locked up and won't relax....
Pets needed food today so dh and I went to the store and whew!!! HOT doesnt even describe it. It was 9am and we thought... lets go to the store early when its cooler out... yeah right!! The air in the store wasnt cold enough so we took the motorized cart and strolled thru the freezer isle for me. That did it!!
