Question by andrea q: What are three respiratory diseases that cause shortening of breath?
These diseases have to be non-fatal, seeing as I'm using it in my story and I don't want the character to die. Please, if you could just tell me three non fatal respiratory diseases that would be great :)
Also, how long each on takes to cure/treat.
No more links, please.
