If that video is for real, and it sure looks like it, that was exceptionally good information for ice anglers.
I have sent the link to my sister-in-law who was a top-ranked researcher (PhD/MD) into cold weather effects on the human body and did this kind of research all over the place. I am highly interested in her take on the video, and I am guessing she knows the researcher who is the guinea pig. Human physiology in cold weather sports is not exactly a huge research area in Canada..............
I will post her reactions. In the meantime, I am believeing what I saw.
