@izzy it was a bit under 35 degrees c today in the uk
it wasnt comfortable, but it was tolerable. then again, i was sitting an exam in a room with no air conditioning, wearing a shirt with full-length sleeves and full-length trousers
with clothes with better passive cooling i could probably tolerate that sort of temperature for extended periods, provided that i have somewhere that is actively cooled to sleep (i always have trouble getting to sleep in hot weather, which is not helped by the fact that i live in a room at the top of my familys house (which has four floors, the topmost of which is subject to extremes of temperature so its always freezing in the winter which is tolerable since i just put more blankets on my bed, and boiling in the summer which is less tolerable))
