Shall we start a club, Marian?Just think I'll be one of the lucky ones that will have three knees replaced!
I already qualify.I can get down and up again, but it's very ungainly. I can kneel on my newest TKR knee for short periods, but not on the revised knee. I think I got so used to getting up using my left knee (the newest one) after my revision, that I tend to still rely on it.Another new first today was trying to figure out how to get up from the floor.
I remember very well that I couldn't understand why my mother would not get down on the ground, as she said she couldn't get up again. At that time, I just thought everyone could do it. Now I know better!

Apparently I turned off two alarms. Usually my dogs would wake up 

but they slept in too. So since no one can start their dialysis treatment until I'm in the building I went into warp drive. I live over 30 miles away on top of it. I jump into my car
and heading there going well above the normal speed limits. I ran I to the building at 640. 31 minutes to get dressed and drive there which I believe is a new world's record!

They did have a nice leather couch that I sat on and put my leg on. Well then I fell asleep.
Hopefully I didn't start snoring too. There was a TV on near to where I was sitting. As I was waking up in heard someone on a talk show say that they went to bed in the clothes they were going to wear to work so she wouldn't be late. My eyes were still closed and I laughed out loud after being late yesterday.
I'm sure a few people in the waiting room must have thought what is wrong with that woman. I wasn't able to help my friend with her errands because I had 2 other places I needed to get to before I could get her and traffic was jammed.
