I have a crackling, barking cough. 

I never cough.

I have aches and pains, and the occasional shattering migraine, but never coughs. 

I associate coughing  with weak people, pigeon chested and snot nosed or dirty smokers. 

I think of myself, arrogantly, as strong and tough and free from coughing and sniffling.

Just one more indicator that things are not always as they seem, or as I need them to be.
