ABSTRACT
In his book The Wellness Revolution ( Pilzer, 2002 ), economist Paul Zane Pilzer suggests that in 2002 existing items in the US wellness industry such as spas, fitness centers and vitamins had reached approximately $200 billion. This includes $70 billion for vitamins and $25 billion for spas and fitness centers – about half the amount spent to purchase US automobiles. Pilzer further suggests that the $200 billion is only the tip of the iceberg, and wellness products and services represent the beginning of a new $1 trillion sector of the US economy. In an updated edition of his book, Pilzer estimates that in 2007 the wellness industry had expanded to over $500 billion and that the untapped market for wellness had increased in size due to millions of new wellness consumers ( Pilzer, 2007 ).
