D.Robin Hood Returns to the City

Uhoh, the new year's just begun and already you're finding it hard to keep those resolutions to junk the junk food,get off the couch or kick smoking. There's a biological reason why a lot of our bad habits are so hard to break—they get deeprooted in our brains.
That's not an excuse to give up. Understanding how unhealthy behaviors become deeprooted has scientists learning some tricks that may help good habits replace the bad.“Why are bad habits stronger? You're fighting against the power of an immediate reward. We all as creatures give greater value to an immediate reward than something that's delayed,” says Dr Nora Volkow, director of the National Institute on Drug Abuse.
Just how that bit of happiness turns into a habit involves a pleasuresensing chemical named dopamine(多巴胺). It trains the brain to want that reward again and again—increasing the connection each time—especially when it gets the right cue(暗示) from your environment.thus destroying attempts to get rid of bad habits. Even scientists who recognize it find it hard to resist.“I don't like popcorn. But every time I go to the cinema, I have to eat it,” Volkow says.“It's fascinating.”as some companies offer employees immediate payments for adopting better habits. However paying for behavior turns out, researchers say there are some steps that may help counter your brain's hold on bad habits: repeat,repeat,repeat the new behavior—the same routine at the same time of day. Determined to exercise?Doing it at the same time of the morning makes the brain recognize the habit eventually. If you don't do it, you feel awful. Exercise itself raises dopamine levels, so eventually your brain will get a feelgood hit even if your muscles protest. Reward yourself with something you really desire, Volkow stresses. You exercised all week? Stuck to your diet? Buy a book, a great pair of jeans, or try a fancy restaurant.
