Morticia,

thought a lot about your jolly good question.
I played a lot of instruments in my youth, now only the treble recorder, stopped plucking the guitar.
Most I enjoyed singing in the church choir and blowing the big bass in the church brass band. In 1983 I had a nasty car accident (my life was saved by the US Medical Corps, they found me first), but I lost my voice and a big part of my lung volume.
If I could swap today, I would give my LEFT HAND for being able to sing and play again like in former times (for the bass the right hand would suffice, the pressure to the mouth piece could be done with the stump of the left).
