I had just finished a workout when I watched this, so I thought I'd try the cold shower. As soon as I touched the water, I backed out, literally. I ended up setting it to warm and working my way down to cold while in the water. It was a challenge, but I did it and I feel good about that!

Other benefits of cold showers:

• use less water (because it's hard to stand it for long)
• use less electricity
  -- to heat the water
  -- to run the fan afterwards (there's no steam when the water is colder than the room)

Thanks for the encouragement, @humanearl! Maybe tomorrow I'll go outside shirtless. To be fair, it should be around 45-50 degrees, so not as bad. :D
