Seriously, why?
Why would you end you day unconscious and virtually paralysed, leaving yourself open to attack by all and sundry?
What's the point of it?
What do we gain from it?
One person described sleep as the brain de-fragmenting itself.
Some seem to think that dreaming is a crucial part of out existence.
30% of our lives spent in limbo. OK I made up the number there but it is a lot.
So, why sleep?
