Everyone has heard the centuries-old adage "laughter is the best medicine." But few may realize the words of real wisdom inherent in this cliché: scientists have proven that laughter does, in fact, increase blood circulation, strengthen the immune system, improve the functioning of the brain, and dramatically reduce stress level. This unique documentary discusses the emotional, physiological and psychological benefits of laughter in full and rich detail, drawing on interviews with such notables as Regis Philbin, Eli Wallach, Danny Aiello, Doris Roberts and Joel Osteen. ~ Nathan Southern, Rovi
