In the battle of the generations, entrepreneur style, who would win--Boomers or Gen-Yers? According to a recent study by OPEN from American Express , it'd be a close tie. Believe it or not, both generations actually agreed on several key issues. For example, both agree the economy is strong and opening their business was a good idea. "It's good news for the economy when both the established generation and the generation representing the future of small business are optimistic about economic growth and their own success," says Susan Sobbott, president of OPEN from American Express.

But there are also several instances that didn't bridge the generation gap. About 75 percent of Gen-Yers, ranging in age from 18 to 29 years old, say that 'having fun is a priority in my business' compared to about 66 percent of Boomers, in the age group of 42 to 64 years old. Passion was the driving force for 55 percent of Gen-Y business owners when they started their business, compared to only 40 percent of Boomers. One of the largest areas the generations couldn't agree on is risk-taking. About 72 percent of Gen-Y entrepreneurs say they like to take risks, though only 53 percent of Boomers could say the same.

Have you heard of "exergames"? How about "exertainment"? If you're under the age of 15, chances are you're one of the trendsetters already doing it. But adults are only just starting to become interested in this growing fitness trend . Exergame machines, also known as interactive exercise equipment, are no longer just for kids at arcades. Some machines are making their way into high-end gyms, YMCAs and sports training centers. Their appeal: They're actually fun and don't feel like exercise.

Some game and video makers are convinced that exergames will eventually replace traditional gym equipment. But so far, the traditional gym chains haven't caught on to the trend. Only a handful of Bally's have Dance Dance Revolution, a popular, high-energy dancing game in their children's area. ClubSport, a chain based in Northern California, Oregon and Nevada, also offers video-integrated bikes. Critics say exergaming machines may seem too complex to adults who aren't familiar with Wiis or Xboxes, and that adults will dismiss the machines as being too kid-friendly and not enough for a serious workout.

But exergames are helping schools across the country fight the growing childhood obesity epidemic. Schools are using Dance Dance Revolution in place of PE in some states and more than 1,500 schools are expected to be using the game by 2010.
