[ 168 ]

There are 7days per week x 24hrs per day = 168 hours in the week. 

If we allow 7x8hrs=56hours for sleep and 7x2hrs=14hrs for ablutions and general time, and say 40hours+10hours/week=50hours for work plus commuting, that adds up to 120hours allocated for full-time non-work-from-homers.

168-120 leaves 48hours unallocated per week.  Say exercise is 7x2hours/week=14hrs (allowing for changing etc), and 8hours/week for shopping and errands, that leaves 36hours unallocated.

Meals? Maybe a generous 1hr each, that’s 3h per day: 21h per week on mealtime. 

That’s only 5 unallocated spare hours left. 

168-56(sleep)-14(ablutions)-50(work incl commute)-14(exercise)-8(shopping/errands)-21(meals)=5 spare hours!

No wonder we’re so “busy”.
