Yeah how far back have they been doing “heat index” numbers?
Heat index could be 10 degrees warmer than real temperature.
Just another set of “facts” made up to bolster a totally bogus argument. Scares the hell out of snowflakes.
Human beings are actually highly adaptable animals, and a young person in a good state of health, with a little physical conditioning and use of common good sense, can endure some pretty adverse conditions. You really don’t have to be young, just adopt a practical attitude and strategies for coping with the extremes of weather, taking advantage of technology and the application of moderation, and almost nobody expires merely because the temperature is elevated.
