This is how I got through my youth when I had to work in the sun (wet bandana) Anything that gets you wet with some air flow. It’s like sweating without to electrolyte hit. Works better in low humidity, of course.
I’m lucky now because I have AC and can just stay indoors through the hot part of the day. I still make the house a dark cave after trapping the coolest air I can from overnight.
For me, it’s about context and scope. The wide open wonder of my youth has been replaced by little epiphanies of experience. A bite of really good food, or music, or a great joke can bring me a startling amount of joy. A lot of my awe has also been replaced by satisfaction and appreciation. Getting old sucks undeniably, but there are compensations.
