WAKE UP

YOU DON'T NEED TO DRINK COFFEE TO WAKE UP . . . JUST SMELL IT:

If you're hitting up Starbucks for a pick-me-up at least once a day, you're blowing about a grand a year on coffee. But here's a way to save some money and get the buzz for free . . . walk into Starbucks, take a whiff, and leave. That's right . . . just smelling coffee can actually wake you up the same way drinking it does, according to scientists from South Korea.

Normally you down a cup of joe because the caffeine makes you feel less like a zombie. But scientists found that antioxidant compounds in the aroma of coffee also gives you pep. They did an experiment with two groups of sleep-deprived rats . . . and the group that was allowed to smell coffee became less stressed and more awake than the group that didn't smell coffee. If the same holds true for humans, you might be able to experience the effects of a cup of coffee without ever drinking one. - Nazzy
