Is there actually any evidence that shows this sort of thing is valuable to make kids do in the middle of a school day? PE always just seemed degrading to me, and I’m not even that out of shape.
Run a mile in the cold? Well I wouldn’t know, I hate running.
But I’ve snowboarded in 4C and couldn’t wait to get down to my t-shirt after a few minutes. Hell, even walking for too long in that thing sounds like an awful mistake.
Tell this to people living up north: Was in GB once for work. There I destroyed my winter jacket. Shopping around for a new jacket I met several guys wearing shorts an t shirts. I was freezing and they walk around casually like it was summer!
