A pretend PSA about maintaining a balance between what you eat and how much you move. It's what I'm spending a lot of my time in grad school researching, and it's one of the many things in life that is so simple, yet so hard to do. Personally, I'm especially proud of the rolling cookie. (But I truly can't say why the sound didn't work and the image quality deteriorates at the end. It looks great on my computer! And I've been trying all day to get it to work online and have finally decided to go with this.)
