> Otherwise, theoretically you can "overwork" i.e. (work more than standard 40 hour weeks or some standard of work hours) whatever without compromise

That's simply not true. Humans aren't machines. Productivity falls off a cliff after 50 hours, and after 55 you may as well not even be in the office. There are diminishing returns with "overwork"ing.
