"my last 3 universities I attended..."
Forgive me, but I chuckled reading it, and I know Ok can be brutally hot and humid in the summer.
I also remember thegrobe asking you years ago if your occupation was an impetus for this topic, and you demurred. I contrast that with some others here that love to boast of their so-called education, and I'm well aware that the smartest in the room never feel a need to express it.
Many of us here have wondered about your physical condition, but, one thing that has impressed many is your intellect.



just drank more water and Iced coffee 
Gotta admit, I don't deal with the winter part as well as I did even 15 years ago. Nosebleeds, cracked hands, and, most especially, using a cane on slippery surfaces were not problems for my first few decades. But I never did like the heat, even as a kid when I could at least tolerate it, I still hated it. I always figured why bother being warm blooded if you're just going to surround yourself with air and water that's pretty much the same temperature as your body?
I haven't lived in the south since I was a kid (Oklahoma) but I've still had my share of heat and humidity since then. Check out this coincidence: my last 3 universities I attended were at latitudes of 42.73 N, 42.03 N, and 42.28 N, in order. Each university was more than 550 miles from the one before it, but the total range of latitude was 0.7 degrees. And all 3 locations gave me more than my fill of days of 90+ degrees and what felt like about the same percentage humidity. UGH!
