There is no time like the present to flip your anger into absurd, cackling, fake laughter. It's a known fact that your physical body doesn't really know the difference between real laughter and fake laughter.

The endorphins and physical joy comes back into your system, fires up the happy side of your brain, and can bring you part of the way back to center.
