Hello, @dieterreuther. I had an interesting conversation with one of my doctors during a recent hospitalization. I noticed that two of my medications appeared to have opposite objectives, one 180º from the other. (I wish I could recall the names of the two medications.) When I questioned the doctor about this, he initially seemed a bit defensive ('No, no, Ray, you don't understand … '), but after he'd given the matter more thought, said, 'Mmm? 'That doesn't make any sense, does it?' ––Ray (@ray666)
