At 4h 30m a day, you will spend about 15.5 waking years of your remaining life looking at a screen. Book estimate assumes 6 hours per book.
How this is calculated
Remaining years = 80 − your age. Total hours = daily hours × 365 × remaining years. Waking years = total hours ÷ (16 × 365). It is an estimate, not a prediction, but it shows how small daily habits compound. Read how to block TikTok for real.
