Running.
Jumping.
Your heart keeps on pumping.
Goose pimples run upon your arm.

Throbbing.
Thumping.
Your heart keeps on stomping.
When you can't feel your feet on the ground.

Shaking.
Breaking.
Your heart keeps on aching.
The feeling of despair may come around.

But it's better when it's aching, or stomping or pumping, 'cause if it stops-

You won't be able to hear a sound.
