When I was being taken to hospital after wrecking my leg on a motorcycle, I asked the medical team if I'd be able to play the piano once the injury had healed. No problem at all, they said. Good, says me, cos I couldn't play one before.
Get well soon Marlin. Hoping for full recovery. If you have a metal splint for your thumbs you should get the edged rounded off and see if you could use it to play a lap steel,slide or something. Sorry for the bad joke. Get well you Marlin.
