Ive gone swiming in water at freezing temperatures quite a few times, both intentionally and not. I found initally going into the water was a slight shock. The worst part though was once I got out, had to get dry clothes... You guys Better hope you have a dry pair in the car or partner who can loan you some.

One lesson learned was one day when I went in about 10 years ago. Unlike the video, I found initally going into the water was only a slight shock and getting out didnt seem that hard either. I started to walk to the car which was a mile away. Started to feel colder and colder as I walked while soaking wet in the freezing cold air. I tell you, one thing I should have done that day is just start jogging for the car (and clothes) as soon as I got out.
