With all of the bad s**t that goes on in the world, it's great to hear a story like this. I've signed up to the donor register and I carry my card. I also give blood as often as I'm allowed to. I benefitted from an organ donor 10 years ago myself, and that act of kindness stopped my world from crumbling.
I hope that one day I can do my bit to pass on the chance of life to someone else, so that they can live longer than they they expected to.
