If we can't breath 100% oxygen, how much can we breath?  Obviously our 
bodies have adapted to suit the environment that we are living in, which 
I think is about 21% oxygen.  Although I'm a physics teacher, my background 
knowledge in biology is dreadful, but I was asked this by a student the 
other day.
