a: High blood pressure ~
b: high pressure in a pipe
What:
"About 1 in 3 Mainers are told they have high blood pressure, also called hypertension. Many people do not know they have it because there are usually no symptoms. High blood pressure is like having high pressure in a pipe. It damages the pipe, but you often don't see a problem until it bursts."
