Healthy Choice Entrepreneurs are: A) fit as a fiddle; B) keeping doctors in business; C) about to drop dead? The answer might surprise you.

It's no secret that many entrepreneurs put in long hours, have high stress levels and don't get a lot of downtime. It comes with the territory. But, in the long run, how does an entrepreneurial lifestyle affect your health?

When we sent questionnaires to Entrepreneur's Hot 100 business owners asking them to identify themselves as "healthy" or "unhealthy," everyone picked "healthy." Contrast those answers to the results of a recent study by James M. Rippe, a professor at the Tufts University School of Medicine, and you'll discover a serious inconsistency. Rippe's study indicates corporate executives are at high risk for serious health problems. So what gives? Are entrepreneurs really in good health? Or are they simply in denial?

"I work out every day," says Robert Blomstrom, 44, CEO of Workplace Interiors, an Irvine, California, office furniture company. "It makes me feel better about eating the inevitable cheeseburger that I grab at lunch, as opposed to the salad I'm supposed to eat." For entrepreneurs like Blomstrom, who quit smoking 10 years ago and runs five kilometers per day, good health is a way of life. For others, the issue is a bit more complex.
