Old man is 80 attempting to clean gutters (that I've already cleaned). Ladder would be 2.8m high. When I wasn't looking he moved the ladder which I had anchored and tethered at the correct angle on flat gravel. At 80, doing it in inappropriate footwear, moved it to undulating wet grass with a running hose (going all over the ladder).
So I gave him a lecture on how fucking stupid that was. He didn't take that well.
Just last month putting blinds up inside, he was scaling a step ladder in socks.
it is honestly one of the most rational fears anyone can (and should have) with DIY stuff (same at worksites). Stats for falls (especially at that age) from that height are shocking.
(Hmm, just realised I have no links markup button.)
Anyhoo, facts: risk of falls is higher post surgery. Does he really want to risk a break or joint replacement (NOF breaks do not equal fun). There will be pain, recovery and restrictions.
Not to mention all the other nasties you can do.
Nothing is a good as your own stuff is you if don’t need it replaced. (Pride before fall. Pun intended.)
And I'll add to this that the 12 month mortality rate post hip fracture for those over 65 is around 50%. It truly is life changing and not in a good way.
