Thanks for the gws messages. I'm already doing my arm extensions after googling above mentioned issues. They hurt, but it's all good, all Internet related material says its so important to start these ASAP after the initial injury. So mtfu and getting on with it.
As for riding the bike, I MAY be able to convince her that mtb-ing is a compromise. My dear lady has already said riding in fields is sensible.
I do understand her anguish, 1 major major (could have been fatal) mtb accident and now this latest not too bad an accident, doesn't look good from her perspective.
Luckily I do like hill walking and have amazing routes literally on my doorstep and have the gear already, on the upside, my family like walking too - a no brainier now I think about it.
