Going outside today? Read this first. Even experienced outdoor people get hypothermic, I've seen it, treated it, and had it. This a really good article on the topic, worth reading. Very timely too, since it is classic hypothermia weather today, 6 degrees Celcius and raining (that's 42 F for you metrically challenged folks). Think I'll put on my drysuit and go for a hike.
Good article. Reminded me of a piece by Tim Cahill from many years ago but I couldn’t find it to link. I think I probably read it on paper pre-internet.
