I have been in Texas a long time, didn’t have indoor AC until I was about 14...
Now I find anything over 75 to be kind of warm and 80 to be hot.
lol
Old age and old age drugs seem to make me much more sensitive to heat.
I used to go the the race track and bake in 90 deg sun all day without a care.
Now 10 minutes on the deck and I’m ready to sprint inside.
