This is prepare students for winter break. Hobbies that make you happy are as important in life as careers. This lesson contrasts a food diet (not the main point of the lesson) to a media. The analogy is that junk food/media makes your body/brain sick, but good food/media makes your brain healthy. Also, you can watch consume to much of the good media too, just like how you can consume too much good food.
