sweat!?

Serious question and I admit I am not always serious.

My mother was hot natured, I can also sweat like a Russian racehorse ( they sweat a lot). Genetic I guess. I am 71, had a triple bypass , will be 2 years this Sept. SE Tx is hot and humid and not enough wind generally.
I have always heard that as you get older harder to take the heat. I am in and out of it all day, doing what I want to do. I get wringing soaked, and go cool off. Just wondering is the blood thinner, and blood pressure meds has something to do with it or just what it is?
I don't intend to cash in my chips in the easy chair watching re runs of RoadKill!
