More than three-quarters of the nation's 17- to 24-year-olds couldn't serve in the military, even if they wanted to. They're too fat, too sickly, too dumb, have too many kids, or have copped to using illegal drugs.
The armed services are willing to grant waivers for some of those conditions - asthma, or a little bit of weed. But the military's biggest concern is how big and how weak its potential recruits have become.
"The major component of this is obesity," Curt Gilroy, the Pentagon's director of accessions, tells Army Times' William McMichael. "Kids are just not able to do push-ups... And they can't do pull-ups. And they can't run."
23 percent of 18- to 34-year-old are now obese, up from just six percent in 1987.
The group of potential enlistees is further slimmed by the "propensity to serve" among American youths, which social scientists say also is declining. According to Gilroy, research shows that about 12 percent of all U.S. military-eligible youth show an interest in military service.
