ok so my teacher yesterday got on the topic of obesity, in my human growth and development class, she said there are viruses you can catch that will cause you to be obese.... her words were that you could be in an elevator and someone sneezes and you catch a virus that will cause you to rapidly gain weight and make it very hard to lose... i haven't done any research on it but it sounds odd. she also went on to say that if you exercise and eat healthy(keeping your immune system up) your body is more likely to fight off the virus. what do you guys think? bs or possible?
