First up, I went for my 2.5 mile benchmark walk. Striding along, feeling fine. No sign of breath shortness or weakness. So the valve isn’t breaking down, or at least not much. I will try the gym equipment again tomorrow. It might be some side effect of the drugs I’m taking, who knows.
In the afternoon I completed my carefully phrased, positive not negative, cooperative not contentious, list of problems with the auditorium sound system. Not quite sure what next; I could pass it by my A/V committee? Or go direct to staff with it.
