It starts on the mouth,

And rockets down.

Down to the stomach,

Where it goes back up.

It hurts,

But it feels good.

My mind eases,

Disregarding the bad.

My cheeks ache,

My sides hurt more.

My body relaxes,

My eyes see less.

They close and for a moment,

Everything is happy.

If everyone could do this for a decade,

No one would be sad.

For through the pain,

Misery can heal.

(Note: If no one caught it, every other ending word is an antonym to the other. Either that, or the two are quite different, such as with 'moment' and 'decade,' and 'mouth' and 'stomach'.)
