Although I really have no idea whether TV inhibits the formation of useful memories (I'd be interested in seeing some statistical evidence on the topic), I can, from first-hand experience, support Eben's suggestion to meditate as a means of relaxing. I always thought meditation was either hippie BS or something for exotic eastern religions; however, last semester when I was having trouble dealing with stress, a close friend suggested I try breathing exercises as a form of meditation. It only took me a few days to get the hang of it, and despite my skepticism, I had to admit that it was a great way to clear my mind and relax after a long day of class and studying. I don't really know whether it helps or hurts my memory, but I can understand how it has persisted as a form of relaxation for thousands of years, despite the invention TV, a far flashier and more scintillating form of leisure. I think, in the end, my positive experience meditating stems from Daniel and Adam's earlier comments that it is much more a question of what you do with the medium, than what exactly the medium is.
