Winter has officially arrived, and the plummeting temperatures can make you just want to crawl under the covers and sleep until spring arrives.  But there is a cure for this condition:  go out for a brisk walk!  You’d be surprised how quickly your body warms up by walking briskly–even in very cold temperatures.  Walking is a wonderful form of exercise that you can continue to do well into your “golden years”, and it’s great for clearing your head and shaking off cabin fever.  Check out Dr. Weil’s advice about walking.
