> It’s common to rack up 4 hours or more of screen time a day on your phone. Here’s one way to see the cost of that: every 20 years, you lose 5 years of your waking time looking at your phone.

This is interesting because I suspect most people use their phone while doing other things. I’m in a meeting commenting on this article with my phone. I’ve got maybe 15min a day of “I’m only paying attention to my phone” but I have 4-5 hours of phone screen time. Maybe I’m unusual though.
