Used to play violin & recorder, the moved onto clarinet, bass clarinet & tenor sax.
Played at a decent level in a jazz band, we won a national competition, then went to uni and gave up. Hmmmm. Kinda the opposite of your OP, really.
Got the tenor sax and clarinet out a few weeks ago to show my nephews and could just about play them, but forgotten a lot of what I knew; even fairly simple music. Rubbish, really.
Just don’t have the time. Current things I don’t have time for are: photography, learning woodworking, learning wheel building, riding enough to get fit, getting all the decorating done. Hmmmm.
