@Desertdi I'm in Michigan, we get really cold this time of year. In early November 2018 I fell at the roller skating rink. Here's the corker, I didn't fall down hard or crash into anything. It looked like I was slowly taking a knee. Suffice it to say, that ended my experiment with rollerskating because I jacked my knee up. I had to put ice packs on it when I got home (well, after I stopped the bleeding
). I was on the sofa dying because I was so cold. I didn't know what was worse, the knee pain or the cold from the ice pack.
I worked with a guy who decided to go to a Cryo Spa. Here's the description from the website:
"Whole body cryotherapy is the exposure of your skin to temperatures of -238º to -274º Fahrenheit for a short time (3 minutes or less). At this extreme temperature, your heart pumps more blood into your body, which activates several mechanisms that have significant long-term medical and cosmetic benefits".
You take off most of your clothes; I think he kept his socks and underwear on and stepped into a chamber and let himself being exposed to the temps described above for like 3 minutes. As he was telling me about it, my jaw dropped. He said would you ever try it?
I said, naw, it would give me cardiac arrest 
There are times when you must speak, not because you are going to change the opposing side, but because if you do not speak, they have changed you.
