@roger,
Haha, yeahhhhh, guess not.
I'll just relax and pretend the ocean water is a beautiful, sparkling, clean, crystal stream as everyone else seems to do.
& hahaha wow. To think about it, like you said, how many people had the air that I am now breathing, in their lungs before me? Interesting.
Except for the fact that their bad breath and whatever else that came out alongside with their exhaling breath, has long been lost as the ait traveled to my airway.... Hm..
