My family had boats since well before I was born, so I was a water rat as a kid.
I started diving on compressed air one night when a shrimp boat that was next to me in Key West Bight was sinking and needed an external patch. Holding my breath and trying to do the patch wasn't working. Someone asked me if I wanted a SCUBA tank.
Next day the local underwater repair guy found me and told me how stupid I had been. At first I thought he was just trying to "protect his turf," but not so. He taught me a lot about basic SCUBA stuff and we became friends. I still keep in touch with him.
Several years later all the shops in Key West required C-Cards to fill a tank. So I finally took a course (YMCA) in 1977 at 27 years old. The guy who had originally helped me learn SCUBA was one of the two Dive Instructors in the Keys, so I took the course from him.
Funny thing is that after I took the course (I was the infamous holdout [getting "friends" to fill my tanks for me]) *none* of the shops actually asked to see my card. I guess they all knew that I had taken the course.
I got into recreational diving by accident also. I was living with a woman in Austin TX and we were planning a vacation. She wanted to go to Hawaii. I didn't know it when I met her, but she was a recreational diver. The topic never came up. So the Hawaiian vacation was going to be a dive vacation of sorts.
I made the mistake of telling her I had been certified "way back" and she bribed me back in the water with a complete set of top quality dive gear and a trip to Hawaii. Remember that in the 70s there were no BCs, Computers and the like. A J valve was a nice thing to have, but not all tanks had one. Shops had pressure gages, but none of my friends did. A Bourdon tube was used for measuring depth. It only worked well in shallow water. Also, we had learned to never come up faster than our bubbles. Im not sure how fast that is, but it sends the alarm off on the dive computer.
Lets say it took a while to become accustomed to the new world of SCUBA. Anyhow after a period of adjustment, I found I like recreational SCUBA and am becoming mere serious about it.
Last year I moved back to the Keys and got a live-aboard boat and plan on doing a lot of diving. Id like to do the Bahamas this coming summer and perhaps the Caribbean next year.
