We will all live decades longer than our grandparents and parents and will have better health in our later years. With this enhanced longevity, we all want to look as young as we feel. Especially because we are inundated with images of youthful beauty on television, in films, and in glossy fashion magazines, we feel social pressure to improve our appearance. Aspiring to maintain "eternal youth" and to look good is not new and is not just superficial "vanity." Our human nature dictates that we take care of ourselves and enhance our appearance. Throughout history, women from Cleopatra to Marie Antoinette to today's movie stars have used cosmetics and nutrients to beautify and rejuvenate. Indeed recent psychological studies have proven that the better we look, the better we feel, and the healthier, happier, and more productive we become.
