Society was built to make money. Indifferent to your health and sanity. For example, we did not evolve to: + sit 10 hours a day + have our attention fractured 300 times daily + compare ourselves to millions of others + travel 9 time zones in 13 hours + tolerate sounds above 85 dB causing hearing loss + outsmart algorithms hijacking our reward system + breathe fine particulate air pollution + live under 16+ hrs of artificial light a day + have 3 courses of antibiotics before age 2 + eat ultra-processed foods for 60% of daily calories + consume 17 teaspoons of added sugar a day So if you're feeling down in the dumps, maybe fatigued, a little or a lot depressed, anxious, that's why.
