気になる (to weigh on the mind)

It's always the nights you can't sleep that the ticking of the clock gets on your nerves.

I guess it's just human nature to get hung up on things like that...

If you include 'slightly concerned,' over 70% of people say they worry about pore size and skin texture roughness.

The thing itself is a cause for celebration, but there was one comment that caught my attention.

It really doesn't bother me that much.

I'm concerned about my wife's dry cough.

I don't mind hot weather either.
