Police Officers tend to come in two flavors when it comes to the idea of work and rest. The first is always at work. The 80 hr a week guy. The someday the spouse is going to make the calculation that he/she can have all your money and none of your time or half of your money and all of someone else's time.
The second is the vacation bank at zero guy. The 35 hr a week guy. The counting days till he/she can burn a sick/return/vacation/holiday guy. The why did you ever pick this job because you hate it so much guy. The selling real estate off his/her cell phone in the squad guy.
I have been both of those guys throughout my career and I have to say both have significant downsides. The blend of rest and work is always the best way to go. Strange how that Bible thing keeps saying to do what is best for all of us.
By the seventh day God had finished the work he had been doing; so on the seventh day he rested from all his work.
