How this calculator works
Screen time for the years you have already lived, plus a projection if the daily habit stays put until a life expectancy you choose. Your phone’s weekly report is a better input than a guess. Past hours = days alive × hours/day. Future hours = days left × the same daily habit. Example: 3 hours/day from age 16 to 35 is already more than a full-time year. Keeping it to 80 adds several more years of glass.
