I read a fascinating sociological study some years ago which suggested that observing a day of rest makes sense even from an pragmatic, atheistic standpoint. The study noted that it was common to work seven days a week in communist countries, and this was a major factor in their substantially lower productivity compared to the West.
NO ONE SHOULD WORK EXCEPT THE NFL.
As a matter of courtesy to observing neighbors, I will not cut my grass on Sunday if I just absolutely don’t have to because of impending weather. And I agree, taking some time during the week for self-reflection and nonwork leisure is beneficial.
