I can't imagine a life where one has to work 7 days a week. I think our lifespans would be 20 years tops if that were the case. And I think we got off a bit lucky that we got 2 days in the weekend because the original intention was to work 6 days a week and rest on the 7th day.
How do people do it back then with working 6 days of the week? I'm glad I'll never know.
