I understand that a higher
blood pressure (say, 135/80 and up) does more damage to
blood vessels than the lower readings. My husband and I both, after sitting quietly, and taking it a few times! can get readings at home of about 120/75 or even lower. The first reading after sitting down might be 135/80. But we both are very active (both 54) and run around all day at work, and when we check it then, it can be as high as 140/85 or so, sometimes higher, sometimes lower.
