You work 40-50 hours per week, while 1800s manufacturers worked 60-70. Hunter gatherers living in the harshest desert climates hunt only one day out of three and gather about three to six hours a day.

On average, hunter gatherers lived to 35, though those who made it through childhood often reached their 60s or even 80s. After the Agricultural Revolution, life expectancy dropped to 20 years. It started climbing after medicine lowered infant mortality; average 1920s people lived to 30. Sources: Sapiens, LSE, WHO
