Said “Thomas Edison”.The problem is: He was wrong.

 Russell Foster disagrees with the prolific American inventor. “We marginalize sleep, and think of it as a luxury,” said Foster, a circadian neuroscientist who studies the sleep cycles of the brain.

We get grumpy when we’re sleep deprived because our brains are finely tuned to circadian rhythms and at night, it wants to sleep. If you’ve fed your brain caffeine all day, it will stay awake — but still feel tired. Ordinary work will get harder, you will make more mistakes and they’ll make you mad.
