I moved to Korea and every year June, July and August I’m incapable to be outside because of the humidity. On the way to the convenience shop my underwear is already sweaty.
So I stay either in the office or at home running the AC all the time which doesn’t help with fighting the climate change.
The overweight is probably a big factor for me too. And it makes sense, the fat is a good isolator and keeps the heat inside, once the sweating doesn’t cool you down you become miserable.
