Sometimes I think about how even the number 40 is totally arbitrary. If we made the norm 30, would things be that different? It's such a sad thought that ~half (if not more) of the time we are alive, we spend at work, mostly doing something we don't like. Then I look at this from a cosmic prospective, where we live in this tiny little planet inside a huge universe we barely know anything about, and yet we were able to create a system of living with one another that requires us to do something we don't want to most of the time!
