I bet that's the response of most. I myself am basically glued to my phone :V But sometimes I go out for a walk without it, and I feel... Free but at the same time oddly empty and sort of exposed? If anything "happened" I wouldn't be able to tell anyone/call anyone immediately. I don't wear a watch so I won't be able to tell what time it is. Etc. I do remember a world in which mobile phones didn't exist, but I was a kid back then, I had tons of other things to play with and think about so it wasn't really the same thing; when I became a teenager, mobile phones started to become a thing even though they didn't have color screen or anything yet.
However, I can definitely spend a day without being at a computer. That's just how some weekend days or general days off turn out. But then I'll have had my phone instead d: definitely addicted to electronics here, or rather, the sense of being "Online". Pretty spooky, when you think about it.
