Whats the Longest time a Human can stay up before needing sleep to survive?

Question

How long? because i dont belive a human can go for over 4 days with no sleep.

Answer 1

I once observed (part time) an individual playing drums for seven consecutive days (perhaps the drums helped!).  He was allowed a 5 minute comfort break (but no sleep) once every hour.  Sleep deprivations presents a risk of mental damage (don't try it at home?).

Answer 2

ha! tweekers can go alot longer than just 4 days!

Answer 3

One man has gone 30 years so far with no sleep...

So yea. humans can go a long time.
