Your choice or not, if you stop, you loose your ability so quickly that's disgusting. When I butchered my finger in 2017, I stayed put about 2 months to not take a chance with the skin and nail grafts. No tree, no chainsaw, even no homework. What a pity ! The first small job left me exhausted. I spur climbed a spar, only about 26', but at the top my legs were checking and were full of cramps back on the ground.
Eventually I came back on form, but now I see my father staying for most of the day (and days) in his armchair in front of his computer, sleeping here for hours too. He struggles with his legs in the stairs, walking or even only staying upright. I told him that he has to keep moving and working around the house, it's mandatory to maintain the body in an as good shape as possible. But no way, it's too easy to stay quiet, doing nothing physical and seeping the screen.
I can understand that easily enough but he's 82 now and I fear there will be no coming back now, only worser and worser.
