Section 4. Listening/Composition

Scientists have found evidence to suggest that certain forms of obesity could come from a virus and be contagious in the same way as the common cold. Researchers looking into this theory have revealed that simply washing your hands could be a preventative measure to avoid obesity. This rudimentary practice could improve the lives of millions around the world. This unlikely proposition was made by Dr. Leah Whigham of the University of Wisconsin. She determined that a human virus, called adenovirus AD-37, causes obesity in chickens and could be responsible for the similar condition in humans. The notion that viruses could lead to obesity has been a contentious one among scientists for many years. Dr. Whigham is convinced that factors other than poor diet or lack of exercise may play their part in making people unhealthily overweight. Testing is still in its preliminary stages and further research is needed to ascertain sufficient data to verify her claims.
