I’m not familiar with the research but I will say that conclusion “feels” right to me.

Have they found a modern day metric that we should all be hunting in our quest for reading health? A literary equivalent to the daily 10,000 steps?

Maybe 10,000 words!

Is there value in identifying the difference between reading a longer article like this one and an actual book? Reading the news from the AP/Reuters and a book on history?

I spend lots of time online, primarily on my phone, reading. I don’t watch videos and I don’t use social media aside from browsing the Reddit front page. I try to justify my online escapes because I’m reading a substack, a bit of news, an interesting HN link about someone’s project.

I know I’m fooling myself. Closing the door on the internet and opening a page on an ereader or a physical book is absolutely a different activity. While the content of the book is important (and hopefully well written and captivating!) I regard it now with the added benefit of exercising my attention span.

An interesting book I read called Peak Mind makes the simple point that your life consists of what you pay attention to. Since then I’ve been trying (and failing, and trying) to be more conscious of where I spend my attention and how I can strengthen it against the well researched and incredibly effective distraction engines in my daily life.

Think of it like this: overhead power lines require you to dig a 5-7’ deep hole that’s 2’ in diameter every 90’. Underground power supplied through cable requires you to bury the cable minimum 3’ in the ground in rigid ductwork the entire 90’. Any time that cable runs under a roadway that ductwork needs to be encased in concrete. In urban and semi urban areas you also compete with other buried infrastructure for space - sewer, city/municipal infrastructure, gas, electrical transmission, etc.

While underground distribution systems are less prone to interruption from bad weather it depends on the circuit design. If the underground portion of the circuit is fed from overhead power lines coming from the distribution substation you will still experience interruptions from faults on the overhead. These faults can also occur on overhead transmission circuits (the lines feeding the distribution substations and/or very large industrial customers).

Underground distribution comes at a cost premium compared to overhead distribution. It’s akin to the cost of building a picket fence vs installing a geothermal heating system for your home. This is why new sub divisions will commonly have underground cable installed as the entire neighborhood is being constructed - there’s no need to retrofit underground cable into an existing area and so the costs are lower and borne upfront.

It’s more cost effective for them to turn the power off as a storm rolls through, patrol, make repairs and reenergize then to move everything underground. Lost revenue during that period is a small fraction of the cost of taking an existing grid and rebuilding it underground. This is especially true for transmission circuits that are strung between steel towers over enormous distances.
