That depends.
If it's in a swimming pool, no, not so much. If it's in pirhanna-infested waters, absolutely.
However, I would like to show my support if you're planning on it. I'll even loan you some of my training equipment to help you prepare. Of course, my training equipment is basketball stuff, but hey, it's the thought that counts, right?
So I'll be glad to get my weight vest out to you....
