Do not go against her, go with her. Way with her. TB is a horrendous disease, and is hereditary and regular checkups are required.   Love this idea and will run with it as soon as she starts talking about the possibility of having TB.   Feed her brownies with medical marihuana before she goes to visit relatives. They will hit like a ton of bricks and unlike ajoint you cannot stop smoking it, it keeps going.   The bad thing about this is I don't think she's ever been stoned. She would legit think she's dying and call EMS.  The wiping stick thing is good too but I wonder if they have something similar for painting your toenails. BC that is where she has the real problem with her fat. She can't sit in a chair, prop her foot up and reach her toes.
