blood pressure

High blood pressure is sometimes called "the silent killer." This is because it is dangerous but has few outward symptoms. As the heart pumps, it pushes blood through the arteries, creating pressure on the artery walls. High blood pressure means that your heart is having to work extra hard. Nearly two out of three adults 60 or older have high blood pressure! Besides age, other factors make it more likely your loved one, or even you, could develop high blood pressure.
