Have you been thinking about starting to exercise?  It's time.  A new study done at The University of Texas MD Anderson Cancer Center in Houston found that even as little as 15 minutes of daily exercise can lengthen your life.  The study followed 416,175 adults' exercise habits for an average of eight years.  The researchers then compared these habits with the participants'  health outcomes.  The reported result was that those who reported exercising for as little as 15 minutes a day extended their expected life span by three years compared to those who did not exercise.  The exercising the participants reported could be as simple as taking a brisk walk.  The study reported by Xifeng Wu, MD, chair, of the department of epidemiology at MD Anderson noted that an even better target for even more significant benefits is a goal of 30 minutes per day.  So it's time to get up and get moving.  If you are having trouble getting started, a motivational session with a clinical hypnotherapist may be just the ticket to get moving.
