This just straight up isn't true for blue collar and service work.

I've worked those kinds of jobs with 12 hour shifts pretty recently, and you definitely Really Actually Literally Work 10+ hours of em'. It's kind of a buzz.

I could still do it, 6 days a week, day-in day-out at 32, which was pleasantly surprising to me as someone who has always struggled to work a good 4 actual hours of white collar shift.

Some jobs just come at you non-stop, and basically your only options are quit dramatically, or keep grinding through.

The camaraderie with your work colleagues is something too. I've never felt that kind of genuine, manic, expendables-in-the-trenches, darkly comic camaraderie in any white collar job.

There's something in it though, I wonder if it's just as simple as how 'physical' it is - if you're sort of 'exercising', obviously anything manual labour is, but also walking around, reaching up to shelves, etc. then it's more continuously doable. Tired and hungry sure, but doable.

I couldn't keep my brain continually engaged in SE for even what would be a short 'shift' - but I reckon I could still do the >12h full days I did at the cinema as a teenager (plenty to do even while all screens are showing).
