I guess it’s what we get used to and our summer’s of recent years perhaps decades haven’t been that hot for such a long period
I’ve two friends one from central Russia one from Slovakia and there not happy until it’s above 35 c and they window clean all day in it and absolutely can’t get enough of it, it often what they would get most summers
Me I don’t mind the heat, I just cover up, wide brim hat, no sun screen, try to finish before 3 when it really starts to warm up some times not though
