Each person could be different........also depends on what they are doing.............If setting down a long period of time, they may not last as long awake..........do not be doing anythig dangerous

it really depends on the person some people who are very fit can go as long as 3 days other people can only manage only 24hrs also you have to take in to count that your age can affect the how you would respond to no sleep I would think in your twentys you could stay awake a lot more than if you were in your teens as you are still growing and in your thirtys you could probably manage 36 hrs and so on

18 hours

I read in the "national enquire" that a man went 15 years without sleep, eggplant can verify this story...

On crank, five days. oops, I mean 20 HRS.
