My first college P.E class was a scuba diving course. It began a life-long love affair with the ocean for me. My second was fencing, which to me is like physical chess. Great fun, and a hell of a workout!
I suspect that you would have eventually become involved with scuba diving anyway. However, if a student is required to take a PE course, then it's a good idea to expose them to a variety and let them chose one that they may find enjoyable and stay with for the rest of their life. Did you do foil,sabre, or épée?
