There is rather scant evidence of two-shift sleep presented here; a single quote from some unknown writer and a single experiment with broadly interpreted results. I'm not convinced.

A single quote? There are whole medieval books about what to do “between the sleeps.”

I'm curious about them; what are some titles?

Strange that. I'm not really responsible for getting edible food, drinkable water, warmth, cover, shelter from the elements, protection from hostile animals or enemy humans. I also don't have to actually make anything with my own hands. So, yeah, indirectly I do some of these things by earning a salary, paying bills and buying stuff, but I not sure that the work I do day to day is much more complex or responsible tha…

On a daily basis? No, I don't. And I live 15 minutes outside of the nearest town, a mile from my nearest neighbor, so if I get by driving once or twice a week, surely those who actually live in cities can get by without driving as well.

Point taken.

Though currently during the pandemic the amount of driving I'm doing is limited and tends to low speeds and short distances.

I found it ironic a few years ago when I did a bungee jump that the jump crew had no significant jump injuries after more than a 100k jumps, but they had lost several crew members to road accidents.

Not to mention that the "single quote" in the article is hardly from a "unknown" author (Charles Dickens), this BBC article on the same topic [0] has several other quotes from well known literature in the same period.

Less than 5% of the people I've known didn't have significant driving associated with their work.

This is over decades, across different metro areas.

The most dangerous part of a ski day is usually the drive.

You seem to be disregarding the countless unplanned for things that people assume aren't going to clutter up their lives. A tiny, tiny portion of the things that consume meaningful time each week: trying to turn health insurance into usable medical care or g…

I read your list. It’s very comprehensive.

I’d wager an average person from any previous century would trade places with you in a heartbeat.

Indeed, I bet an average resident of many third-world countries would do the same.

In fact, I bet the average resident of the average trailer park ten miles from where you live would trade places with you.
