After decades of running and one bad trip at zero dark thirty on Fort Knox, I have a knee that decides not to work well every so often.
I'm glad your operation went well. A hip takes a lot of abuse.
As far as a band name, I belong to the over 55+ World of Warcraft guild called "Ancient Artifacts" with players in their 60s and 70s and I've heard there are some in their 80s.
