事实其实是这样的

Have you gotten your fill of exercise this week? If you're an adult living in the United States, a safe guess would be no.

A new government study estimates that nearly 80 percent of adult Americans do not get the recommended amounts of exercise each week, potentially setting themselves up for years of health problems.

Researchers at the Centers for Disease Control and Prevention (CDC) analyzed survey data collected from more than 450,000 U.S. adults ages 18 and older who were randomly phoned across all 50 states.

• ＋1。 写給国内人看的东西一般都把美国简单化，肤浅化，没有全面深入看美国。 -Jolene22- ♀ (304 bytes) () 08/14/2016 postreply 09:22:47
