It’s that time of year again, folks. As the Labrador puppy of hope runs headlong toward the closed glass door of inevitability, millions of otherwise rational adults indulge in a practice commonly referred to as “making new year’s resolutions”. Despite initial confidence, most participants will fail to maintain their resolutions. Following on from David’s piece on new year’s day, I’d like to take this opportunity to provide much-needed moral support (“outside interference”?) to those who are looking to beat the odds and stick to their resolutions. And what better way to provide incentive than by giving examples of how three common new year’s resolutions can positively affect your brain and your immune system.
