What does the evening screen cost over 40 years?
The Evening Screen
2 hours, every night, for 40 years — the long-term cost is 1,217 days.
How the number's built.
The screen is the easiest rest available. An effortless transition after a day of work. But two hours every night for 40 years becomes 29,200 hours — 1,217 full days of attention, given to a stream before the day has ended.
One hour of other activity, not two.
608 days returned.
No rush. It keeps until you want it.
