Don't feel too bad. Wonky knees and hip seem to come with age...hahaha! Been using the old stick for a few years now and a knee brace occasionally. Like @bigtom13 says, the stick comes in handy when out for long walks. Somedays I don't need the assistance but other days I do and I am grateful when it is with me.
I will be keeping a hol dof the stick I think and see how it goes. Normally I embrace some things but I feel it is too soon for me to be sticky! :OD
