I hadn’t considered this one as a particular challenge, but life conspired to put me to the test. I’ve damaged my right shoulder. It’s a rotator cuff injury that makes certain movements extremely painful. Putting that arm into a jacket sleeve, doing up a bra or seat belt, reaching across at an angle. Oh yes, and using toilet paper. I’m right handed so I’ve been learning to compensate with a series of altered movements and techniques. Some tasks just need the other hand so my very clumsy left arm is having a lot of new experiences. It’s a good test of patience and willingness to be incompetent as I perform familiar actions with an arm that finds them alien.
