What do you call mildly high? It seems every ten years they redefine high blood pressure numbers down an extra ten points.
Of course they do...gets more people onto the Big Pharma gravy train.
I do not worry so long as my blood pressure remains BELOW 135/85. Because I do aerobic exercise every other day. Even at age, 82, my EKG is always normal, I do not have chest pains or irregular heart beats. Resting BPM 66.
As we get older, it is natural proces that arteries are not as supple as teenagers. Harder arteries will increase blood pressure. It is simple hydro-dynamics at work. Blood pressure pills can not cure that.
Best thing to do is regular exercise to minimize fat plaque buid-ups in arteries. That plaque build can cause strokes and heart attacks.
