Hey Fred, Welcome Back !! Now be really nice to those Physical Therapy folks and visiting nurses, and of course your children who show up..
Now, remember all those times you were 'a bit strict' with your kids?? Well its PAYBACK TIME.
Glad you are back at home.. And as mentioned already, slow and steady !! Don't be pushing the 8n when it gets stuck, or lifting bales of hay.. Let the young'uns do it..
