title: By the way, doctor.  When I attempt to go into the outdoor pool at my beach club, I gasp for breath, get dizzy and light-headed, and have to get out.  Several years ago, I read an article that some people who are very sensitive to cold water may sustain a heart attack from submersion into cold water.  Is this a possibility?
