People were happier in the stone age than they are in first world countries today.
Our brains did not evolve for the lifestyle we're living today.
I sure as fuck would be happier out hunting, gathering and making handcrafted tools during the day, then telling stories by the campfire wrapped in a fur at night.
Even if there's no toilet paper, I could get mauled by a bear every day, and if not, the tribe will leave me behind on the next migration when I'm too old and weak to keep up.
I'd rather live 30-60 years like that than edit another Excel sheet. Sadly, our "civilization" made that way of life completely impossible.
