& the health of others

I worry about a person's chronic cough 

Is it this:

Well that person doesn't worry about it and is not coughing right now...

So back to the dental issue which is annoying but not as bad. Or maybe an excuse to scream or something. Or complain, at the least, about unfairness. And maybe realize this should get better. Why not. It wasn't always that way. So, get smart about how to handle that sort of health issue is maybe the next thing to do now.
