Sense of Smell

Does swimming effect your sense of smell? My wife and I recently had a lovely dinner with a person very knowledgable about wines. We are both wine lovers and appreciated his wonderful "wine lesson". However, when he got into the description of the wines in terms of berrys and oak and leather etc I had to stop him and say that I can sometimes detect a raisin taste or maybe even a blackberry taste but I have never been able to get any of those other subtle tastes that the wine experts use to describe wines. So he asked me if I had sinus problems or something else that might effect my sense of smell. Well, the only thing I could think of was chlorine. Does anyone have any thoughts or information on wether 30 plus years of swimming and breathing that wonderful chlorine smell could have ruined or at least altered my sense of smell? If so I may go to exclusively drinking 2 Buck Chuck!!! Glenn:)
