interesting facts
While I was doing my research, I found out somethings that I did not know before. For example: did you know that you have 1500 miles of airways? Some of the other facts were that you have 300 million Alveoi,in your lungs. In a minutes time, you breathe 13 pints of air (wow)! That the world record for holding your breath after inhaling pure oxygen is 17 minutes and 4 seconds. That a 30 year old person in good physical shape consumes twice the oxygen of an 80 year old person! Add to these facts, that this is all done automatically with no thought and that's pretty neat!!external image moz-screenshot.jpg
