"Reports that say that something hasn't happened are always interesting to me, because as we know, there are known knowns;there are things we know we know.We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns-the ones we don't know we don't know."

The Facts on Hypertension
by C. Markus www.gooddeedsmall.com
Blood pressure is defined as the pressure exerted by blood circulating on the walls of the blood vessels, and it is one of the common vital signs. Our hearts pump blood through our arteries and throughout our body. It is when people develop high blood pressure (hypertension) that problems can arise.
A normal blood pressure range is considered less than 120/80. People at risk for hypertension are considered to have pre-hypertension, which is blood pressure ranging 120-139/80-89. Anything higher is considered hypertension. Stage 1 high blood pressure ranges from 140-159/90-99 and Stage 2 high blood pressure is anything 160 and above/100 and above.
It’s estimated that 1 in 3 U.S. adults have hypertension. Unfortunately, the condition usually shows no symptoms at first; people can live with hypertension for years without ever knowing.
Some common causes and risk factors of high blood pressure include:
Excessive salt intake
Lack of physical activity
These are only some of the known triggers; in the U.S., the causes of hypertensions cannot be determined in as many as 95% cases. This is why it’s very important to know your blood pressure, even if you are feeling fine. Be sure to visit your doctor and get your blood pressure checked periodically.
If left untreated, hypertension can lead to life-threatening problems, including:
