Healthy Lungs people:

"Do you smoke?"

"Is it contagious?"

"That doesn't sound good."

"I don't want to get sick, can you move?"

"Don't you take treatment for that?"

Chronic Lung Conditions People:

"Why do people smoke? Most of us didn't have a choice of whether or not we wanted good Lungs."

"Yeah, mhm, sure it's contagious." *Coughs on you*

"Well no crap, what do you want me to do about it?"

"I'm not moving just because I'm dying next to you. If you don't like it, move your own butt." 

"Treatments don't exactly stop you from having symptoms."
