This could save your life.
BOOST.
Absolutely vital information to have if you live where the waters freeze over.
I especially appreciate this guy's commitment to actually showing the steps himself. That cold-shock response is a bitch and willingly subjecting himself to it couldn't have been fun.
I don’t live anywhere near water like this, but I am still memorizing this knowledge because:
* I might use it in a story someday.
* Any knowledge that staves off the dying is good knowledge.
interesting. I have used the "relax" technique just in cold Windchill situations... like walking across a college campus in December and January. I would be shivering and shaking and tenser than a curtain rod in a doorway. And then I would relax my muscles and all of a sudden I could stop shaking. I had no idea this was a real thing, but I told a few people who were suffering to just relax and they thought I was crazy. But it just works.
