Wow Mike!!
My Mom also had only her second knee replacement done Tuesday also in tejas. But then she's 86,...that means you've really accelerated the plan.
She ain't goin' for the third knee job in two more years, that's physically impossible unless she goes for the gender change/transplant procedure at the same time. Currently medicare will handle that only if ya had yore tubes tied.
We all need to git all the parts replacements done while we can...when the u.s. Medical industry shuts down in a few more years and moves to greenland and out of reach of congress, we'll be doin' the diy approach to surgery like we do on junkiron!
