Forward head tilting during texting puts enormous stress on cervical spine of neck

There is a newer phrase called text neck. A soon to be published study from Dr. Kenneth Hansraj, chief of spine surgery at New York Spine Surgery and Rehabilitation Medicine shows that it puts enormous pressure on the neck and upper back. 
His study found that bending your head at a 60 degree angle to get a better look at your selfie is putting 60 pounds' worth of pressure on your cervical spine. That's more than the weight of the average 7 year old!
