Description
When I made my first SCUBA dive (Self Contained Underwater Breathing Apparatus) to the bottom of a swimming pool in 1969 I knew I was hooked. Now, after almost forty years and thousands of dives, I am enjoying sport scuba diving more than ever and have already booked my next trip to Aruba where my wife and two sons will join me in diving in crystal clear water along spectacular coral reefs. It was with great pride that I became certified as a Scuba Instructor with the Young Men's Christian Association (YMCA), the National Association of Underwater Instructors (NAUI) and the Professional Association of Diving Instructors (PADI). Over the years I trained and certified hundreds of men, women, and children as sport scuba divers. When students signed up for lessons, they completed a medical history form. Many physical conditions traditionally are considered as "contraindicated" to sport diving. In the past, having chronic ear problems would have kept a person from diving. Changing pressures while ascending and descending underwater means a person must "equalize" the pressure in the middle ear with the same pressure as the surrounding water. Air moving into and out of the middle ears by way of the eustachian tubes equalizes pressure.
