Question: how long would it take to watch all 16 seasons of grey's anatomy?
Answer: Since you need about half the day to eat, sleep, and generally be merry, it'd take you around 19-20 days to binge all 14 seasons of Grey's Anatomy. If you consume Grey's like it's your job (8-hours a day), BingeClock estimates it would take you 29 days to watch the series in its entirety.
