Dr. Alan I. Leshner, head of the American Association for the Advancement of Science and former director of the National Institute on Drug Abuse at the National Institutes of Health, calls addiction the "quintessential biobehavioral disorder."
Biology vs. behavior
"Modern science has taught that it is much too simplistic to set biology in opposition to behavior or to pit willpower against brain chemistry," he wrote in the journal Issues in Science and Technology. "Addiction involves inseparable biological and behavioral components."
This year, the top three New Year's resolutions are to lose weight, to save money or improve finances and to quit smoking, according to FranklinCovey, a Utah-based company that helps individuals and corporations become more organized and efficient. Other goals include exercising and improving family relationships.
As for Herr, he doesn't make resolutions. Not that he thinks he's perfect.
"I believe that it's important to try to constantly make change throughout the year," he says. "If you really want to improve the quality of your life, you're constantly doing an index of yourself."
