The invention is very good, I sometimes feel so handy with my phone but we should realize when to stop it. I had downloaded a game some time back and I realized I was getting addicted, not only that even my eye sight was getting affected, it was so much luring but 1 fine day I just decided to uninstall and stop it and I was so much better after that. We should realize that there are many other important things to do in life then spending all the time on the phone.
