Sir, I don't know this is an illness or just a habit. But my father is like slave of mobile phone. He is 52 now. He can't stay a second without mobile. Sometimes I have seen him to play with mobile after midnight and before 4 a.m. At the same night. Means sleeping time is sometimes less than 4 hrs. About 7-8 years ago, when I bought computer he used to play a stupid card game on it whole day and upto 2 or 3 o'clock at night. It went on for 3-4 years and when he got a smartphone, he was like crazy for that mobile and only thing he did on that was playing that card game. But from last 6 months he started watching stupid videos on YouTube and now he spends more than 5 hrs on YouTube and 3-4 hrs on that card game. No matters who come to home, he can't stay without that more than a limited time. He just want to have a phone or computer every time with or without reason. He can even do official work on computer whole day with so much excitation. We all family members are so worried about it. I thought to take him to a psychiatrist but I know he will never be agree. Please suggest me what should I do?
