It seems to me that several points of discussion have been left out. Most of you know where I'm coming from...my MS has taken away my ability to sing and also my fine motor skills. That means I can no longer play Chopin on the piano. And though I'm learning dulcimer...so many tunes are for accompanying singing (like strumming the guitar). Whistle, fiddle, and pipes are better in groups. I just saw a melodeon up close for the first time last year. I played clarinet as a teenager, but can't get a sound out of it now. The harmonica also seems limited, even though I love "Goodbye Old Paint."

So John, back to your question...as others have said, play the instrument you love. But also consider:
1) Will it be for your "solo" enjoyment or group playing?
2) Will you sing along with it?
3) How much musical background do you already have?

Above all, JUST DO IT!
