What does the deferred call cost from age 30 to 65?
The Deferred Call
30 minutes, weekly, age 30 to 65 — the long-term cost is 700 hours.
How the number's built.
Thirty minutes of catching up is easily postponed. The week gets busy, and the connection waits. But calling once a month instead of once a week over 35 years is 1,400 fewer calls. From age 30 to 65, that compounds to 700 hours of conversation lost to drift.
Calling twice a month, not once.
210 hours of connection recovered.
No rush. It keeps until you want it.
calling twice a month instead of once (12 extra calls/year)
12 calls/year × 0.5 hours = 6 hours/year saved
6 hours/year × 35 years = 210 hours recovered
30 minutes / call saved
40 calls / year missed = 20 hours / year lost
20 hours / year × 35 years = 700 total hours of conversation missed
