10 hours really seems extreme. I am certain that the vast majority of office workers could produce the same level of output at a 4x9 schedule as they do in a 5x8 or would in a 4x10.
And most would be profoundly happier people.

There are large differences between people regarding their strength, physical endurance and intelligence. Why not mental endurance?
I would like one day a week when I'm not working OR looking after the kids, however. That would be amazing. It would be great to give it a try and see how it worked out. Unfortunately my employer is a hardass and doesn't even allow work from home, let alone fewer days a week.
I don't know any parents that do that - literally never interact with their kids 4 days out of the week. What actually happens is parents sacrifice their kids' sleep schedule.
I understand working like crazy for things like starting a company/grad school/career change, but those things all last a limited time and come to an end.
Then you have others who are more used to billable time or flex work or similar where they view that 5-6 hours (+ breaks and food) as an '8 hour' day and the two can't understand how the other manages.
Lucky is the person who can throw themselves at problems 10+ hours a day and look forward to going back to it the next day, I guess. I can easily and happily do that in the 6-8 range and feel proud of the previous day's work and be ready to do it again the next day.
