Obesity can be viewed as a disease. I would say around 2/3'rd of Americans are overweight and this somewhat lead to the idea that obesity is a norm. Technology also does not help as it makes more things automated and leaving you less work to do. There are several signs to know if you are overweight or not. You see the bump of fat all around your body. You have difficulty breathing, can't run for more than 10 seconds before running out of breath, the lid of the ketchup jar is too tight for you to open normally but your younger sister can do that easily.
