The health and fitness industry has been stimulated by increasing consumer interest worldwide, resulting in high growth in revenues and profits. The industry in the U.S. exceeded $35 billion in revenues in 1984. Health spas and resorts, representing a major part of the health and fitness industry, have grown in popularity and offer high investment potential. Revenues from spas in the U.S. presently are estimated at $10 billion annually. The number of spa-goers is projected to grow from 31% of the adult population in 1987 to 41 % in 1995. The most traditional type of health spa is the geothermal spa, featuring baths and pools of natural hot mineral waters. Profitable hot spring spas and resorts are found in most geothermal areas of the world. As an example, the approximately 2,000 inns and hotels with hot spring spas in Japan generate over $6 billion in annual revenues
