More retirees opting to launch startups

(Business 2.0 Magazine) -- Terry Alderete and Leonard Liu don't seem to have much in common. She's the owner of a special events firm in Newark, Calif., and he's chairman and chief executive of a software development company split between Silicon Valley and Shanghai. But Alderete, 61, and Liu, 65, are both part of a booming demographic: retirement-age entrepreneurs.

For the past 10 years, adults ages 55 to 64 have been the group most likely to start a new business, according to a study released in May by the Ewing Marion Kauffman Foundation, which promotes entrepreneurship.
