Most people tend to have phone with alarming-notifications, so they get informed that they have a message, or email or whatever. The phone interrupts them and directs their attention. They train themselves to be controlled by their phones.
I'd go crazy trying to live like that. I have no audible notifications, and vibration only for actual calls. Everything else: I'll see it when I see it. I tend to think of it as receiving a letter -- I'll see it when I check if there's any post, I don't need to be interrupted right away. Personal space and all that.
It just seems so mentally unhealthy. The same applies to sleeping with your phone in the same room.
