Coupled with the aging of the baby~boom generation, a longer life span means that the nations elderly population is bound to expand significantly over the next 50 years. By 2050,25 percent of all Americans will be older than 65，up from 14 percent in 1995. The change poses profound questions for government and society?of course. But it also creates career opportunities in medicine and health professionsand in law and business as well. In addition to the doctors，we，re going to need more sociologists，biologists，urban planners and specialized lawyers. says Professor Edward Schneider of the University of Southern Californias School of Gerontology .

　　Lawyers can specialize in elder law , which covers everything from trusts and estates to nursing-home abuse and age discrimination ?

Any student who combines an expert knowledge in gerontology with，say, an MBA or law degree will have a license to print money. one professor say.
