A few years ago my brother and I decided to go spend some time on the atlantic coast (in france) in the beginning of november. We got there and it was freezing, raining all day. On the second day a storm came, the beach was empty, you could not tell if someone was standing 3 meters away from you... I was very, very reluctant but he made me put on a wetsuit and go swim and run in the middle of that mess. Of course we had fun, and I was never cold; and he said, this is what reminds you what it is to have a body ! I thought: yes he is right.
