People are just not made for the 40+ hour work week and the current job environment
People as hunter gatherers and peasants used to work more, but the work was slow and easy. Not physically but in terms of brain power.
They worked at their own pace - had extended siestas during the work day and no commute.
Now work is hectic. You have to fulfill the quota.
You have to work the entire 8 hours. No siesta.
You have to think all the time using brain power.
You have to commute.
You have to deal with toxic bosses and colleagues.
You have to work no matter how the weather is.
And even just 100 years ago, there were not 1000 possibilities you could do instead work but more like 10.
So why not work when there is not much to do besides it?
But now you know about 1000 other fun things you could be doing instead working, making work 1000x harder.
