Humans Have Started To Grow SPIKES In The Back Of Their Skulls From Cell Phone Use.

Humans Have Started Growing Spikes in the Back of Their Skulls Because We Use Smartphones so Much

Press your fingers into the back of your skull, just above your neck. If you feel a small spike you may be among people whose body has responded to smartphone use by growing new layers of bone. The phenomenon involves what is known as an external occipital protuberance: a growth which appears on the back of the head. David Shahar, a health scientist at the University of The Sunshine Coast, Australia, told BBC.com that in the last decade of his 20 year career he has noticed more patients have the protrusion which was once considered rare. Shahar explained to BBC.com that when the external occipital protuberance was first studied by French scientist Paul Broca in 1885 "he didn't like it because he had studied so many specimens, and he hadn't really seen any which had it." In a study published in the Journal of Anatomy in 2016, Shahar and his co-author described how he had been spotting external occipital protuberances more often in x-rays of relatively young patients at his clinic. To find out more, he looked at 218 radiographs of the lateral cervical spine, where the external occipital protuberance appears, of people aged between 18 to 30-years-old. A growth had to be at least 5mm-long to be counted as an external occipital protuberance, with anything bigger than 10mm classifed as enlarged. Source
