Those thin people are usually at least still capable of taking the stairs. It isn't even comparable. Unless you are dying of anorexia or have cholera and are already underweight, your thinness is probably healthier than a morbidly obese person. We shitladies don't tell people that they need to be underweight or a size zero, but there is a heel of a lot of difference between a 2 and a 22. You can be a 6 or an 8 without being unhealthy, but not a 26 or a 28. Shit's not possible. Comparing obeasts to underweight people with acute communicable diseases is a strawman argument.
