You aren’t reading or using a hammer for 6 hours a day. It’s hard to find a tone ppl aren’t using their phone that would be appropriate to take it away if it’s only while not using it

Phones and computers are used for more than one thing; in that sense they aren't analogous to a single item such as a book or hammer but rather an entire closet filled with odds and ends. Keeping in contact with acquaintances, checking traffic and looking up other day to day information, reading a book during down time, these are three completely distinct activities that have all been nearly entirely subsumed by screens for me.
