Do you feel weird/anxious if you go outside and don't have a phone with you?
Nope. I sometimes forget my phone at home, no big deal I seldom use it. And even when I don't forget it I have zero social apps or games installed on it, not even email ;)
I only use it to pass phone calls and to manage IDs and finances (and it's only because my banks all require me to use their stupid apps, I would gladly tell them to go funk themselves but I need to be able to access my accounts).
What I never forget and I never hesitate to use whan I have the opportunity is a pocket book, so I always have something to read (without distraction, aka no Internet) and a pocket notebook/pen so I can write stuff (without any distraction, bugs, updates or whatever...) and in both case without any worry about being tracked.
so like its basically social expectation to be on your phone when you are by yourself.
Is it? And then people are surprised they're exhausted, and constantly anxious and/or angry at one another? Doom scrolling is poison for the mind and for the soul. I'd rather look around, or speak with people.
you are missing a lot of information
Do I? Well, so far it has not caused me much issues.
that you might need in case you get lost or something.
When that happens, I ask my way around to people. It sometime is a nice opportunity to start a real conversation ;)
edit: typos and clarification.
I live in Paris, France (hopefully enough of a city to qualify?) but I'm not 'addicted af' (not at all, for that matter) and neither is my spouse, nor are quite a few of the people we know ;)
That said I also see a lot of people walking looking at their screen, bicycling looking at their screen, driving and looking at their screen. And I see a lot of accidents too. I wonder, could there be a link?
