Ear Infections
Slightly off thread - I work as a receptionist at an NHS Out-of Hours centre ie where you go to see a GP evenings and weekends. Well over half of all the ear infections and pains who arrive are people who have been swimming either in the sea or swimming pools (obviously!) I think their condition may be related to the numbers of bacteria present in both locations. The concept of sharing a swimming pool with children in disposable nappies apalls me! Don't let's even think about it!
