I've noticed something at the gym. I usually have the shortest shorts of anyone there. I wear swim trunks, and they aren't that short. The bottoms are an inch or two above the knee. When I was in elementary school we had a dress code. Not a dress uniform, mind you, just a dress code. One was that shorts could be no shorter than about an inch from the knee. I remember measuring the gap one morning to check if it was decent. It was - if I stood up.
That was in the 1970s, and shorts then could be really short. My swim trunks now would fall within the dress code, assuming scaling since my legs are a bit longer now. But I look around and nearly everyone is wearing shorts that go below the knee. I'm always wearing some sort of loose T-shirt, usually from some conference I've been to. I see again that nearly everyone else wears some sort of close-fitting gym clothes. Which probably do a better job of wicking.
It's the middle of summer here in Sweden. Many people are on vacation. The weather is warm, for Sweden. Nights get down to about 12C/54F which means I can be sitting on the small balcony at night enjoying the cool air, so long as I have a sweater on. A few times it's been warming enough to not need the sweater. It's after the solstice and the days are getting noticeably shorter. Around midsummer even in the darkest of night I could see lightness in the northern sky. Now there's a few hours of real dark. Winter's coming. But not for a while. :)
