Some people spend most of their life working 60 real hours weeks, especially blue collar work.
I have a white collar workplace, and there is a big spread. There are people that do 20 hours of real work and those with a 60+ hour average.
I have done 100+ hour weeks of real heads down work & all nighters , but can't/wont do it prolonged.
As skeptical as some people are of merit based compensation, I'm confident that the willingness to pull out the stops and get it done has lead to promotions, raises, and freedom to scale down my workload during slow times.
I think it is interesting that some people simply don't believe that high volume work happens, is productive, or is even possible.
