A Few Curious Atmospheric Numerical Facts and Implications

• The number of molecules in one breath of air is ~ 10²².
   
• The number of molecules in the earth's atmosphere is ~ 10⁴⁴.
   
• An average person draws ~ 2 ´ 10⁸ breaths during a lifetime.

Therefore:

• The number of breaths of air in the earth's atmosphere is 10⁴⁴/10²² ~ 10²² ~ the number of molecules in one breath.
   
• If you were to exhale, thoroughly stir the atmosphere of the entire earth, then inhale, you would get, for an average breath, about one of the molecules you had exhaled in any previous breath.
   
• Each breath you take contains roughly one molecule from each exhalation of every person that has ever lived on the earth (prior to the passing of a thorough mixing time, about ten years) .
   
• Each breath you take contains about 2´10⁸ molecules that were once breathed by Moses, Isaac Newton, Joseph Smith, Brigham Young, Shakespeare, Beethoven, Adolph Hitler, or any other name you choose to insert.
   
• The atmosphere is very much a shared resource!
