Cellphones have changed the face of technology but they could also be changing our skulls, too. Researchers in Australia say that constant cell phone use is causing horn-like spikes to grow at the back of young people's skulls. The "horns" are actually bone spurs that biometrics researchers have studied and say that constantly having the neck tilted forward to look at our phones shifts the weight of the head from the spine to the skull, causing these callous-like growths. The "horn" can be dangerous if not addressed; it can cause terrible headaches and back pain. If you want to avoid the issue, the researchers strongly urge you to be mindful of your posture. Keep a straight back and no slouching to look at that text message! Do you think more physical ailments or issues will be discovered as smartphone use goes on?
