Students, truck drivers, travelers, workers on the night shift all have trouble staying awake from time to time, so when you absolutely, positively have to stay awake, this is what you do.

All of us have been there, so sleepy that it's tough to keep our eyes open. Drugs are dangerous, coffee makes you pee a lot and pulling our nose and ear hair makes you say bad words. There is one sure fire way to stay awake when you have too: Eat sunflower seeds. Not the ones already shelled, but the whole ones you have to work at. There is something about having to work for that little bit of food that keeps your brain awake.

So next time you're cramming for that final, or trying to keep you eyes open long enough to finish that important project, try eating sunflower seeds.
