What does the evening inbox cost from age 30 to 65?
The Evening Inbox
30 minutes, every evening, until 65 — the long-term cost is 6,388 hours.
How the number's built.
Checking work notifications after hours is a small, quiet action that maintains connection to the workplace. But checking messages six times an evening for five minutes each compiles to 6,388 hours over thirty-five years. This is 266 days of waking consciousness spent working outside work hours.
One check an evening, not six.
