question: I am an 89 year old male.  I am 5 ft 81/2 inches tall and weigh about 165 pounds.   I take some vitamines and pills but I am very active and still do some sales work.  My old plood pressure machine stopped working so I just bought a new one that is battery oprated.My wife just took my blood pressure and it was 156/77/66 in my left arm and 147/79/76 in my right arm.  Is that OK?
