July 31 (Bloomberg) -- Steve Case, who stepped down as chairman of AOL Time Warner Inc. in 2003, still draws a crowd. It's April, and he's describing the benefits of yoga and organic food to about 600 people at the 10th annual Lifestyles of Health and Sustainability conference at the Fairmont Hotel in Santa Monica, California. Booths featuring Mum's Original hemp and flax supplements, Numi organic tea and shirts made from bamboo and soy fibers line the walls. Case, who last year started a company focusing on health care and luxury resorts, tells his audience that the U.S. is ripe for a transformation. ``The objective of this movement must be to make healthier, more-sustainable lifestyles available to every American,'' says Case, 48, who's wearing an open-collar shirt and khakis.
