<prompt> Human: I have a total of 11 revolving credit accounts. My average is 4 years and 6 months. The oldest is 13 years and the three newest are 1 year and 10 months, 2 years and 3 months, and 2 years and 4 months. These are retail store credit cards that Im able to close. Two of them have zero balances. If I close these accounts will my average age increase or does it not work that way?  <response>: Average age of accounts is not just opened account but closed accounts too, so this will not work like youre hoping it will.
