Anecdote: Southern Mexico van travel’s high 90°s: My van had A/C, but I decided that if I once started using it, I would be addicted & afraid to leave the van. I opted to just accept it. I owned 6 Roadtrek RV vans and never used A/C.

Anecdote: Yangon, Myanmar temps: Got off the plane from US via China, at midnight in 70°s & high humidity. It hit me like a warm wet blanket. Next day, much, much hotter. I complained to myself & then said, “You knew it would be hot, so quit bitching and ignore it like locals do."   My attitude throughout South America and Asia.
