Trust me: For a big chunk of the population (and not just "older" people), spending four hours a day without screen time is not something special. Insisting you need a screen for not just one, but multiple activities listed makes you an inflexible person. And that is the type of person many employers do not want to hire.

For health reasons not related to sleep, I found I had to reduce my screen time. I'm the type of person who likes everything electronic. All my notes are in a text file, etc. But I did step back and looked at the bigger picture: The cost to my health was clear. The gains on insisting everything be electronic was much muddier. I was spending a lot of time on activities with a dubious ROI. Once you start getting older, the urgency with which you want to make your "free" time meaningful really kicks in. If I didn't change, I could easily see myself in my 50's still sticking to habits that do not benefit me too much.
