Life expectancy in the U.S. has reached a new level, according to the National Center for Health Statistics. According to a report released Aug. 19, average life expectancy has risen to nearly 78 years, an increase attributed mainly to falling rates in nearly all the leading causes of death. The average life expectancy for babies born in 2007 is nearly three months greater than for those born in 2006. In the past decade, U.S. life expectancy has grown nearly 1.5 years.
Japan has the longest life expectancy at 83 years.
