I like to tell my girls that TV will rot their brains, which my be going a little bit overboard, but I have worked to keep their screen time down. Maybe this is why they were always stoked to watch coverage of bike racing? They do watch movies occasionally, and on a plane, forget about it: DVDs are my savior. Unfortunately, once they're tucked into bed, the TV comes on for me and I end up feeling like I've wasted an evening. The Mayo Clinic Diet recommends limiting television time to the amount of time you have exercised that day. This rule may not be as strict as the TV rule I use for my girls, but I'm going to try it.
