I recently read about an interesting quirk involving teenage obesity and Army recruiters. It is one of several factors that results in only 3 in 10 candidates being “fully qualified” to enlist, reports Dave Montgomery writing for the Atlanta Journal Constitution newspaper.

Not being “fullly qualified” forces the service to issue waivers to offset a particular deficiency, depending on the circumstances. Other factors include being a high-school dropout, criminal records and low scores on qualifying tests in addition to teenage obesity.
