NP whos, they say ignorance is bliss, but not when it comes to your health. and best to check your BP at those machines at the store too, cause some people have "white coat syndrome" which means your blood pressure rises when you go to see your doc. i certainly have it, and im not ever nervous about going to the doctor, ever. so if u have borderline when u go to the doc, be sure to check it out in non stressed situations.
