How are our myths un/true?

Recently I was just browsing the Internet when I came across a link that said "Medical Myths: Strange, but true..." immediately I was curious about the the link had in store to read since we had been discussing links previously in class. The link lead me straight to a online newspaper article from the newspaper The Independent in the medical section. The first myth that caught my eye was "Fat People Are More Jolly" and as soon as I read this title I thought of Santa. Normally when we think of Santa the first few things we think are fat and jolly, but in this case the article was about real people. The article stated that according to psychologists at Lakehead University in Canada they found that the hypothesis about fat people being more jolly has been proven to be true. As of now they have found that this happiness is more common in women than in men. From the research using the Body Mass Index (BMI) compared to the mood of the women showed that the higher the BMI then the lower the symptoms related to depression, anxiety, and a negative mood. Personally I feel like people who hear about this article will be confused and indifferent about the results. I believe that when people, especially women, begin to hear this myth is true then more and more people will become comfortable with the weight gain or maybe even attempt to gain weight that is really not wanted. I think that this myth is not true because I have always been told and strongly believe that exercise can help to give a person more energy, self confidence, and all around a better attitude. I think this myth could potentially hurt all people in a way whether they choose to believe it or not. For those who choose to believe it could possible fall into an unhealthy state to which is not wanted. Those who choose not to believe it may be in doubt whether their dedication to a health and active lifestyle is worth all the time and effort, which in return could cause depression for that person. I have found by looking more into myths that they can be dangerous to believe and not to believe.
