<prompt> Human: My thinking is: if I get a bunch of cards now, itll pay off 20 years from now if I just leave open them and charge a few recurring bills to them each month. Wouldnt this help my credit score down the road, by outweighing any new cards that I open in the future and keeping my average age of account high? Im not looking to take out a loanmortgageetc. for at least a few years, and Im not looking to carry a balance on these cards. Am I missing something?Edit: word missin  <response>: Not missing anything. Get a couple cards, use them, pay the bill when it is printed and youll have a great score when you need it.
