If you are like most of us , it will happen 3 more times in your life.
You will go for a while , {my first was 7 years} where pool is not even on the radar, then something will happen and you will start playing again, usually you spend more time learning how to play better and it becomes fun again. Then you get tired of all the creeps and take another hiatus , Rinse and repeat Then the last time you realize you have gotten old and it hurts to play, or you can't see, or a million other things and you quit for good.
I saw less future in lifting weights than pool, being in excellent shape is a great thing, but to me lifting weights was just looking for problems with knees and back in the future for most people. If I were your age, I would take my kids hiking and camping, and teach them survival , they will probably need it, if things don't change drastically.
