  Dealing With Peer Pressure
For example, a few kids in school might try to get you to cut class with them, your soccer friend might try to convince you to be mean to another player and never pass her the ball, or a kid in the neighborhood might want you to shoplift with him.

  Pressure
Pressure in a fluid can be seen to be a measure of energy per unit volume by means of the definition of work.
Pressure in a fluid may be considered to be a measure of energy per unit volume or energy density.
The most obvious application is to the hydrostatic pressure of a fluid, where pressure can be used as energy density alongside kinetic energy density and potential energy density in the Bernoulli equation.

 High blood pressure (hypertension) - causes, treatments and medications
The bottom number, the diastolic pressure, represents the pressure in the arteries as the heart relaxes after the contraction.
The diastolic pressure reflects the lowest pressure to which the arteries are exposed.
An elevation of the systolic and/or diastolic blood pressure increases the risk of developing heart (cardiac) disease, kidney (renal) disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke (brain damage).

 Atmospheric Pressure: force exerted by the weight of the air
Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air above that surface.
Atmospheric pressure is measured with an instrument called a "barometer", which is why atmospheric pressure is also referred to as barometric pressure.
Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.

 What Is High Blood Pressure?
Blood pressure is the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure).
High blood pressure (or hypertension) is defined in an adult as a blood pressure greater than or equal to 140 mm Hg systolic pressure or greater than or equal to 90 mm Hg diastolic pressure.
High blood pressure directly increases the risk of coronary heart disease (which leads to heart attack) and stroke, especially when it's present with other risk factors.

 Blood Pressure - Health News - The New York Times
Hypertension The pressure of blood against the walls of arteries is recorded as two numbers—the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats).
Normal blood pressure is less than 120 millimeters of mercury systolic and less than 80 milliliters mercury diastolic.
If not, if may be necessary to add blood pressure medications such as diuretics, ACE inhibitors, beta blockers, or calcium channel blockers.
