Obvious study is obvious. I wonder if people can think straight when swimming in glacier cold water.
I find the colder the more strongly it encourages sounder decision-making and better judgment in future, as it was clearly such a terrible decision. Then, I don't look forward to really cold water like some must do. I've been in cold water places where I should've known better. Couldn't say if I'd be apt to do that again anytime soon. See? Lessons learned.
