We know that getting a good night's sleep helps with all sorts of health issues. I'm not sure it makes you nimble enough to be able to juggle tables like these two lovely ladies do.
I'm also pretty sure that it won't help you with brain surgery. Some hospital in Houston live Tweeted the removal of a tumor from a woman's brain today. You'd think the doctors involved should be focusing on the surgery?
Getting a good night's sleep also will not prevent a baseball from hitting you in the nards, or protect the same baseball from bouncing off you and hitting your girlfriend in the face.
No, sleep can only improve your brain, beauty, health and attitude. I suggest we all get some more.
