Immigrants live longer than U.S. natives

Immigrants who come to the United States live on average three years longer than people born here. The life span difference reflects immigrants' reluctance to embrace Americans' drive-thru, drive-everywhere mentality and they don't smoke as much. Immigrant black men live nine years longer than black men born in the United States. The average American-born black man could expect to reach 64, while a black man born overseas would likely live beyond 73 if he immigrated. Black immigrants are three times less likely to smoke than American-born blacks and far less likely to be obese. Black immigrants also drink less and exercise more than those born in the United States. the Canadian Journal of Public Health, reported that immigrant life expectancy surpassed 78, while U.S.-born life expectancy hovered at 75.
