Please move this if there is a better forum for it. I have read many things posted about leaving cards open so you do not shorten your average account age. My average account age is 28 months. When I sign up for cards just to earn a bonus wouldn't I increase my average age if I canceled the card after a year, or any time shorter than 28 months? If I cancel the card does that closed account age stay the same (a year for example) and that closed account stay on my report dragging my age down forever more?
