For people who's children have out grown their electric collars ....
I'm not sure how serious the huffington Post should be taken.
Apparently average teens are sending > 100 sms per day, sustained. I suspect that wears out their joints to the point that they aren't able to write any more. Also, the number of teens without finger prints is becoming endemic.
At any rate, the article seems to be sensationalist B$ aimed at scaring parents into subscribing to one of those children's safety services .... in contrast to just supervising your children.
