Hands sometimes don't work as I have Dupuytren's contracture (rare bilateral, it was meds) I'm amused it is common in Nordic folk ( caught it in Norway j/k). can play guitar still but owie. So now I'm working a lot more on voice although I will not give in. I played today outside

Really? It's only hereditary if you have some Nordic/Scandic gene. There are other causes, mine was a side effect of wrong medication and it's moving fast. They want to hit it with the needles. It's not curative, nor is surgery. Not doing that with major blood disorder, FWIW
