The point is that exercise can remove the underlying problem. And those who stay active enough don't develop it in the first place. Doc was amazed that I wasn't on any maintenance meds at 55. (Since then I've gone on blood pressure meds but if other health issues were resolved I don't think I would need them.)

Anybody can spike to 180 in a sufficiently stressful situation. (And, personally, I would very much notice 180. Otherwise calm, I'll probably notice 140.)
