There is now a phenomenon called 'Phantom Vibration Syndrome'. It occurs when someone regularly has their phone set to vibrate. They feel phantom vibrations on their leg - even when their phone is not present. Up to 90% of US University students experience these phantom vibrations.
I was chatting with a parent at school pick-up the other day. She told me that she really enjoyed my presentation on ‘screen time for kids’. She felt as though she now understood the real issues. Then she said that she was feeling really guilty. She still allowed her kids to watch seven hours of DVDs on a recent car trip to Queensland. She explained that there was no way her kids would sit quietly in the car for more than 15min without a DVD to watch.
