I stumbled upon the StarCraft CD key thing myself after my sister broke my original CD and case. I had a ripped copy and tried a pattern until it worked. I was maybe 12 and didn't know what an ICQ was.
I guess I was doing some these things already and didnt know it. Standing desk locked in the up position for zoom marathon days. Stepping back from the screens and camera when there isnt any reason to have hands on kb/m.
I'm a usual pacer when on the phone so I'm not sure if that's instinct or habit but it certainly helps.
Scheduling is also not mentioned surprisingly, but leaving 5-15m buffer gaps between back to back meetings I run is huge. When I dont do that I pay for it.
I am in this boat. Though my phone usage is still there, I'm spending more time on other apps to get the same brain-break, entertainment, or distraction. Reading articles here or following other news sources straight from their sites instead of having a handy subreddit that aggregates them all (example - following Formula1 news).

The point about planned obsolescence is tough to work around. Until we start designing physical devices to make it for the long haul, this problem just wont go away.
