After my Near-death-by-squashing- experience with a tractor and a concrete wall ended in a totally mangled right arm here is my $0.02:
Since I was (then) 48 and had a family I just decided to get on with everything as fast as possible and the phuck the pain and to h#ll with the cosmetics and limitations. So I have a real mess there inside (metallica and scar-gunk) and outside (scars looking like a shark bit me) plus mental traumas still. I just put the bars on the bike a little bit off centre crooked to accomodate the unstraightenable arm and it is all mostly ok. Gave up swimming at all.
But if I had not had dependent kids I reckon I would have been more thorough and put more effort into getting it really sharp. Maybe not 100% but pretty close. I mean all those top sports-people have serious surgeries all the time and come back to world-class form.
All you need is love...la-dee-da-dee-da...all you need is love!
