I went backpacking with some friends when I was in my early 30s, and one night we camped by a lake that had snow on the opposite shore. We decided to go take a quick dip in it. We knew it would be way too cold to enjoy, we just thought it would be fun to briefly experience it just to see.
I'm guessing it's like that. Why do people climb the tallest mountains? It's not fun and they don't get anything for it, they just want to say they were able to.
I wouldn't do either of those things today, but I feel like I'd be a hypocrite for making fun of someone who does.
Yeah, it's 103F (39C) in my back yard as I write this, which is 5F lower than yesterday - it's pretty awful. Those temps actually aren't terribly abnormal for the middle of the summer here in the US Southern California valley I live in, but normally the humidity is barely double digits and it's currently 47 percent, which makes a giant difference in discomfort. They say that the warmer ocean temps (I'm 20 miles from the coast) are making it so the air holds a lot more moisture. I grew up here and the difference between when I was young and recent years of staggering.
