Seems as a Nation we aren't getting our 8 hours sleep, well at least 28million of us arent!
Are you one of those that doesn't get a full 8 hours, is that by choice or do you need less?
Personally less than 6-7 hours i'm cranky, but I can sustain around 5 days with only 4 or 5 hours, then I flake out but the leading question is how productive is one with too little sleep.
I think Maggie (Thatcher) famously ran the Country during her reign on 3 or 4 hours if memory serves and she certainly didn't do too bad a job (depending on your red/blue colour of course)
I wonder how many man hours a day are lost due to unproductive staff suffering with sleep deprivation ?
