At 75 years of age I am not interested in scuba did it several times years ago, I like to just go in from the beach and go out for a couple hours a day, Today I dove down 4 or 5 times about 15 feet and I could feel the pressure. A few years ago I would dive down 20 or more times.
Then one day I got a nose bleed and ever since I limit my dives.
