Activities done per every snorkeling death. It’s a one in a ten million chance of happening but if you are obese, out of shape, drinking alcohol, elderly, taking multiple medications etc then doing any exercise that is not within your normal routine should be done with caution. The problem with snorkeling is people think they can swim but they can’t, they think it’s an easy exercise, it’s not. They think they can do it after drinking all afternoon, they shouldn’t.
