"Can't come in today, boss. Doc says I have text-neck."

How's that gonna fly? Well, it might, because doctor's are now diagnosing patients with "text-neck." It doesn't take a genius to figure out what causes it... too much texting on your phone.

Dr. Adam Rodnick explains that "for every inch the ears go forward in front of the shoulders, we're putting an extra 10 pounds of pressure on the spine, neck and shoulders."

He says bowing our heads down 3 to 4 inches for hours at a time causes our spine to age prematurely. Dr. Rodnick, a Chiropractor, says he's been treating more teens lately for "text-neck."

What can you do? It's pretty complicated: Keep your head up!
