Yes, Jay, I did do that boxing day dip in the sea. It was icy cold, and I got in to just above my waist. Not sure if it was a coincidence or not, but I didn't hurt anywhere near as much the rest of that day, and I seemed to have slightly lower than usual pain levels for a while after. Don't think I'd want to do it regularly though. It was as much about doing it as a group for charity as anything. Am seriously considering doing it again this year though.
