I first heard of this through Wim Hoff. I see older folk swim here on Christmas day. Its supposed to be great for cardio vascular system. For me though no. Id do it if a dog or child fell in but not voluntary for the sake of it personally.
@Wiseacre My god yes. I do like the deep breathing exercises though. I was doing them but my chaotic mind forgot after a while. Maybe i should tune into them again.
