ah but here is a thought y do we sleep? its kinda big evolutionary fail, a body that repairs itself while consious would be a thousand times better

Topic cleaned.

Also, I reckon sleep is the part of the day where the brain processes everything that's happened, discarding whats useless from the memory. While conscious, the brain is working quite a bit on processing everything around us - While asleep, I suppose it only has to concentrate on repairing and allocating everything useful that's occurred, and discarding the rest.
