5 days 13 hours, Me and 4 friends had a contest to see who could go longest. One of my friends fell asleep at 18 hours <--- he had diabetes so he got tired very easy. Another friend droped out at 3 days 2 hours, a third friend at 3 days 9 hours. Then me at 5 days 13 hours. My final friend who beat me went for 6 days then got bored and fell asleep.
