15 minutes, daily, age 30 to 65 — the long-term cost is 133 days.
How the number's built.
Reading product reviews feels like diligence. The distraction occupies a small pocket of the evening. But fifteen minutes of daily comparison over 35 years accumulates to 3,194 hours. That is 133 days of conscious attention given to comparing options.
One research session a week, not daily.
114 days recovered.
No rush. It keeps until you want it.
limiting research to one weekly session of 15 minutes
saves 3,193.75 - 273 hours = 2,920 hours
÷ 24 = 114 days recovered
15 minutes / day
365 days / year = 91.25 hours / year
× 35 years = 3,193.75 total hours
÷ 24 hours/day = 133 days
