I love your facts!!! I'm an insomniac, so sleep facts are especially interesting to me.
The fact about not noticing the effects of sleep deprevation after a while is so true. Last week, for the 1st time in a number of months I was plagued by a bout of insomnia. I managed to get 12 hours sleep across 4 nights. But the 3 day I barely noticed the difference. The first 2 days i was a bit of a zombie.
Mind you, I still don't think I should have been driving to and from work by the end of the week!!!

I have not heard of that one before but i have heard that sharks do it cause if they stop swimming they drown. Something about they shut down half their brain and swim in a circle and when they start it up and shut down the other half of their brain they swim in a circle the other way round.
