In the news recently, "researchers at Baylor College of Medicine in Houston found that a baby's smile activates a region in the mother's brain known to produce feelings of euphoria." That is some ill sheet if I can say so myself.
"The same can be said for money and praise; Japanese researchers have linked both to the brain's pleasure centers. In other words, whether you get a raise at work or a big compliment from the person you're dating, your striatum -- the brain's reward system -- is likely to be turned on." British researchers also found that "successful shopping produces a euphoric experience equal to kissing and other romantic activities."
Did I say this is some ill sheet? (For the link to real article...)
So go give some compliments, look at a baby smile, climb a mountain, give that lemonade stand a buck, and find that deadstock Wu-Wear XXL jacket you've been looking for all this time.
