This has nothing to do with Photography but thought to share it with you.

How quickly does a single blood cell travel around the human body?
An individual blood cell takes about 60 seconds to make a complete circuit of the body.

How quickly does human hair grow?
Human hair seems to grow at a pretty consistent rate of about half a millimeter or so per day, or about half an inch every month.

How many bones are in the human foot?
There are 26 bones in the human foot (28 if you include the sesamoid bones at the base of the big toe).

How much skin covers the average human body?
About 20 square feet (2 square meters) and it weighs about 6 pounds

How many cells are there in the human body?
Between 50 and 75 trillion...humm...do we really think how many cells we loose when we have cut in the skin :)
