You sleep for 8 hours. Another 2 hours is spent showering, prepping for sleep and waking up and using the bathroom during the day. So you have 14 hours left.

You sleep for 8 hours. Another 2 hours is spent showering, prepping for sleep and waking up and using the bathroom during the day. So you have 14 hours left. If you work, you only have 6 hours left. Commute to work? 4-5 hours. Dishes, mowing the lawn, prepping and eating meals, studying for your next job advancement, housekeeping, laundry, etc etc... by the time you are done there isn’t a ton of free time in the day. Spending half of that free time on such a mundane and boring way to pass the time sounds truly impractical to me.
