About the dust...

FYI...

What happens to old cells?
Just like us, cells grow old and die. When old cells die, new ones replace them. For example, a blood cell in our body lives for about 120 days. Another example is our skin cells. We shed our skin cells about every 35 days. Don't worry, we do not shed all our skin cells at the same time like snakes do. In human beings, only the skin cells that are old are shed, others are not.
Here is a amazing fact for you, if your skin cells are replaced every 35 days, by the time you are 20 years old you would have replaced your skin cells roughly about 200 times. (found at http://askabiologist.asu.edu)
