A pencil dive, when you're half way down into the cool deep,
finally realizing how bad you need air.
Then it becomes a struggle, a battle of  pushes and pulls.
It would be some much easier to give up but as your lungs shriek
in despair you know its the last thing you can do.  
So you get over the five seconds of struggle and
you make it back to civilization again.  
You continue this somewhat insane pattern of
deprivation and struggle just to remind yourself
how much you love the taste of air
