Bulldog 19-- I'm glad you enjoyed it. As I said, I have brought it up to my son but with limited time due to a very rigorous academic schedule combined with baseball-- his response is "when." When he graduates from HS in June it will be the first time in 4 years he hasn't had a magnitude of school work to complete-- and that includes his summers. I think he plans on incorporating it then, as they use it at his college. Unfortunately he inherited the same gene PUHD's son inherited. (husky) I'm thinking it could help keep him loose. I know when I ran marathons I used alot of water running with an aquabelt as I got older in order to save some of the wear and tear on my body.
