I think only twice or three times a day.
When I was taking a train, I counted how many people check their mobile.
Around seventy percent of the passengers were watching their mobile's screen.
I guessed that some people were checking e-mail, watching TV, browsing internet or playing games.
Guess what the rest of the passengers was doing?
The rest of ten percent was reading books or newspaper, another ten percent was sleeping. The rest of them was spacing out.
This made me worried about the future in Japan.
There are lots of things to do or interesting things, but most of people were just watching mobile's screen, which means they don't learn anything.....
