But that's not the question, the question was how do you explain to another person why your job is exhausting.
No one said other jobs aren't exhausting, but for example to a classic working class position who works primarily physical, the leap could be bigger to understand why our job can be exhausting too and how could you explain why.
Still I wouldn't compare it to coal mining / steel working exhausting... mainly because our job is not physical harmful by default.
Nothing to do with being humble though.
