Everything old is new again. This phrase can be applied to virtually every facet of our lives. Past trends in fashion and music have reappeared. Generations-old recipes have reappeared as today's "comfort foods". Automotive makers have breathed new life into popular hot rod and muscle car models of old. And even the health industry, despite the staggering advances in medical knowledge, has resurrected ancient techniques to provide comfort and relief to those suffering from stress and pain.
