I resisted from bothering 2 post-share this 4 whatever reason probably 2 MUCH ELSE is going on out there USA-globally but ya know how - when people may no have immediately available a 'Back scratcher', I PAST though (archived in my mind) if whether 1 out there would-might come out with (& easily available at YO local little drug store, misc) 1 ('Back scratcher') about the size of a small bathroom throw down rug-mat BUT affixed - (stick 2, attached, or fasten) upon the wall in YO home, apt, misc & 1 would just walk up 2 it - turn around & have YO back facing up against it & just gently bend YO knee's, misc kind of like a Bear does against a Tree, huh, just a thought smile.
