I will say that having done this for two years I feel great afterward so I'm doing a micro time preference reduction in my head before I jump in.

That's a great experience. I'll bet that if you could do it every day you would, because it's moving, you know it's above 32 fahrenheit/ 0 celsius. And you didn't die after the first try.

When I go in I tense my diaphragm and push out my breath then I'm thinking, "Let's go!" Which is the 29th Infantry motto and my former National Guard Division!
