No, they do not, and most of them aren't willing to understand, either.
People, or at least NT people, with higher temperature tolerance are almost always assholes about it - I have weird heat sensitivity, I suspect on account of my Autism, and I only stopped getting constant shit for it once I basically entirely stopped talking to NTs.
The people in this thread are just seizing on an excuse to shit on people they perceive as weaker, or an excuse to shit on the English as if they are actually inherently evil just by existing. Or both.
I'll defend the islanders and their weak constitutions.
At high enough humidity you can't cool down from sweat, so a 88°F/31°C wetbulb temperature can be lethal. Add in sunlight, combining radiation with convection, which gives the extra 9°F/5°C needed to kill you. Humidity and direct sunlight can make 79° lethal, especially when combined with physical exertion.
It's not just the gout and aristocratic inbreeding that's killing them I swear!
