All three of us are down with a bad cold, but only one of us doesn’t seem to care. While Rachna and I are complaining and cursing about bad headaches, itchy runny noses and watery eyes, bad appetites and lack of sleep, Anika seems relatively unaffected by the blocked nasal passages, as long as. of course, her mind is diverted via toys, books and music. This proves it beyond doubt that your well being is all in your mind. If you think you are healthy, you will be.
