We live in a time of immense wealth, but not leisure.
The average medieval peasant was illiterate, slept on straw, had to work if they were sick and God forbid they broke a bone they would likely have the bone set incorrectly handicapping them to varying degrees for the rest of their life.
The average American has air conditioning, electric or gas heat, a smartphone, watches television several hours a week and rarely has to worry about food poisoning or getting intestinal parasites.
Give up the air conditioning, the car, the 3000$ laptop every 2-3 years, the 1200$ smartphone every 18-24 months, the Netflix/Hulu/Disney+/Spotify subscriptions, never purchase a single item that is (or contains a component that was) imported, the exotic vacations 0.5-4x a year, the 4-9$ cup of coffee 1-3x a day and that food delivery service you use 1-7x a week, running water and all electricity at your residence and you too could work considerably less.

The article also talks about how peasants took frequent rests, but this is because they were doing extremely physically demanding work, not because they had a chill schedule.
Edit: A great example is that in Mexico and the American Southwest one of a woman's traditional tasks was grinding corn by hand, which could take up to 5 hours for her families supply. Other areas of the world that ate grains and didn't have access to mills would have had to spend a similar amount of time.
Cleaning, paying taxes, commuting, exercise (because most workers don't get it at work anymore), buying and cooking food, taking care of house and car, laundry, etc.
I huge amount of time is spent on those things and that wasn't included in the 40 hours.
