My 80+ yo neighbor broke his hip teaming his oxen in rocky woodland.
Toughed it out for two weeks (!) because, you know, you only go to the
hospital to die. So he went to the hospital to die and they put in
a prosthetic joint. The the PT babe comes around and says, "Do thus and
so and the push as hard as you can."

Well, the PT babe sees flabby, weak retired accountant octegenarians.
So Sammy pushes and his new hip simply pops out of its socket. Well,
he's been loading and unloading a cord of wood every day plus feeding
and driving his oxen before the woods accident. Not flabby.

Surgeon resets his hip, chagrinned PT babe does her thing more
carefully. And he doesn't die. Six months later he's out in the woods
again, loading cordwood with his oxen and went on doing that till
nearly 90, the year before he died.

Among people I know, there's a total of 5 hips, all of them success.

ObMetalwork: Circa 1973, an MD friend brought me a metal hip ball that
he'd fished out of the OR sink -- shiny, pretty thing. (Replaced
because of a bad rection to the alloy in that particular
patient. Doesn't happen much anymore.) He wanted me to make a door
knocker out of it. So I did and had it on display at a craft market
where he was to pick it up. Annnnnnddd....

A surgeon came by, saw the knocker and threw a hissy fit. Bad taste, I
had no right, where did I steal it, what surgeon gave it to me, not
right for people to see such a thing yada yada. Managed to get rid of
him before my friend showed up.
