If a 4-day work week reduces stress and makes people happier, how about once-a-month wars on a scheduled day instead of this horrible random death and destruction we have now? Better yet, restrict it to a specific location.
In other words, invite Russia, Ukraine, and Iran (and anyone else feeling belligerent) to join the NFL. It'd be a lot cheaper than $11 billion for one week. And think of all the ad revenue for the countries that participate!
I'll stop while I'm ahead. 😀
