I recall my dad telling a story about the time he went deer hunting up in Canada in the winter, was living rough out in the woods, and after two weeks had grown so gamey he couldn't stand it. So he took a bath in an icy-cold creek. His only report beyond that was that it was probably the shortest bath he ever took. LOL
I do love a nice hot shower, but often turn down the hot water and let the water cool considerably toward the end, especially in summer. It is invigorating, for sure.
Thanks for posting.
