Phone addiction usually starts at a very young age. How?
Parents give the toddler the phone, just to keep himself/herself occupied and silent while they do their household chores, or even thump around on their phones. There are parents who feed very young children with the help of the TV or phone, too. The child is been kept glued to the TV/phone and consumes the food without any interest!. This, we can see amongst todays adults too! This is a universal decease IMHO.
A new study has found a link between symptoms of attention deficit hyperactivity disorder (ADHD) in adults and excessive use of social media, smartphone dependence and internet addiction. The ADHD traits were observed even amongst adults who have not been diagnosed with the condition.
I don't know how far in-depth the above studies had been done, but definitely the warning signals are out and flashing!
