Challenge for the day

Engage in some totally meaningless, spontaneous laughing. If you dare, try it when you're with friends. The benefits are worth the risk of looking silly. I assigned this to my students, and one reported:

I decided to experiment with this meaningless laughing by laughing outrageously loud when something only remotely funny occurred in the show I was watching. I actually really enjoyed the experiment because it made me really happy. The laughing somehow injected energy into my body almost like I had taken a happy pill. After laughing ridiculously loud throughout my 30 minute program I was ready to release my energy which I did by walking through the woods.

Go for it!
