We've collected data on the most sleep-deprived individuals of the 20th century, and the results are alarming.

• The longest recorded sleepless streak: Lee Lee, 37 hours 14 minutes
• The most sleep-deprived celebrity: Angelina Jolie, 3 days 8 hours 42 minutes
• The longest sleep-deprivation-induced coma: Jeff Reeves, 4 days 12 hours 14 minutes
