Sorry I am going to be really, really boring. I swim at a local pool several times a week and these are the best and worst swims. The worst when I really do not want to go and I make myself, all because now and again I get the equivalent of a joggers high and I feel like I could swim forever. Yes swimming in the Med, Aegean, Caribbean, all lovely but nothing like the high I occasionally get and constantly want more of. Not better than sex but one of those physically memorable experiences that we live for.
