Good deal, David! If you can put your foot flat then it is at 90 degrees. To walk and squat well, and ascend and descend stairs, you need to get it past ninety. That's what I am working on.

I am glad you don't mop floors. But, in the event that you ever have to, do it on your butt (lol). That is what I will do from now on.

How are you doing overall?
