Very lucky escape for all of you, thanks for posting.
You sound like an uncle of mine who is very similar, always up to something, but accident prone, his body is similarly beaten up now, after being tougher than a grizly bear, his latest injury was to his back, at the age of nearly eighty, with already two knee replacements and work previously done on his spine, fell off a ladder working on the edge of the roof of his house, we thought he'd never walk again, but he is slowly getting back to his feet.
Thanks for writing your story, I hope you've made good recovery.
