Did You Know?…

The average red blood cell lives for 120 days.

There are 2.5 trillion (give or take) red blood cells in your body at any moment.

A red blood cell can circumnavigate your body in less than 20 seconds.

Nerve Impulses travel at over 25 mph (40 km/hr).  

A sneeze generates a wind of 100 mph (166 km/hr).

A cough moves out at 60 mph (100 km/hr). 

Our heart beats around 100,000 times every day.

Our eyes can distinguish up to one million color surfaces and take in more information than the largest telescope known to man.  

Our lungs inhale over two million liters of air every day.

When we touch something, we send a message to our brain at 124 mph. 

We exercise at least 30 muscles when we smile.

We make one liter of saliva a day. 

Our nose is our personal air conditioning system: it warms cold air, cools hot air and filters impurities.

In one square inch of our hand, we have nine feet of blood vessels, 600 pain sensors, 9,000 nerve endings, 36 heat sensors and 75 pressure sensors.

A person can expect to breathe in about 40 pounds of dust over his/her lifetime.
