It's amazing to me how many people can't seem to walk down the street these days without staring at their phones the entire time.
I think they're addictive, bad for your mental health and acuity, and bad for society. And it's amazing how much time I'll spend even just checking the two small hobby discords I'm in just cause I've been so tuned towards picking up the phone when bored.
Leaving it in the other room on a speaker is nice cause it at least forces me to get up, and since I keep it on the speaker I don't often sit with it anymore. Which means I do other stuff like read, and clean, and work on things, or just sit and stare at the wall and let my brain breathe.
I still use maps (without location though), check out which helicopters and ships I'm looking at, weather, email, search, and Spanish flashcards through Anki. Which I think are nice activities.
