They’ll never get it back. For the first time in 23 years, the life expectancy of U.S. citizens has shortened. According to new data from the National Center for Health Statistics, men’s anticipated lifespans dropped from 76.5 in 2014 to 76.3 last year. Women also lost time: .1 years to an expected 81.2. The drop, which hasn’t happened since AIDS peaked in 1993, is blamed on increases in several types of death, particularly heart disease, dementia and accidents during infancy. Still, people continue to live longer than they did a lifespan ago, when lives were a decade shorter.
