Well, I am sure he feels worlds better, having gotten that out of his system.
I have done some hiking and biking in Florida, New Mexico, and Arizona, and it is surprising how much different dry heat feels. I know it is a cliche, but .... 99 degrees at 99 percent humidity in Florida felt close to death, while 115 in Arizona just felt hot. Crossing the Mojave felt hot, but not as hot as ten degrees cooler in Florida. IMO,. of course.
