Not just mental health but health in general. That said, would it really be desirable?

There's no work-life balance as long as we work 5 days a week and rest 2, imo.

I think that depends a bit on personality, place/time in life, etc.

I could easily pull those hours in my early 20s,etc but nowadays I have family and other things so if I do those hours I'll be behind with other things so in addition to needing a bit of extra rest as I'm older, I'll also be in a "todo-deficit" that needs to be caught up with making for more stress in the near/middle term.

Yup, also, as someone who's done sustained 60+ (maybe even a month of 80+), there's very little room for creativity. It works ok for pursuing the solution to that one clear, looming problem.

I much prefer 5hrs/day of focus, arriving at the office refreshed, excited, and creative.
