<prompt> Human: I am 22. About a year ago I opened a basic credit card with no rewards program and have been using it to purchase nearly everything and paying it off every month.I just opened a new credit card with an awesome rewards program and a Target Red Card save 5 at Target.I dont plan on using the non-rewards card ever again. Is there any reason to keep it open? Will it hurt my credit score to cancel the credit card? If I do keep it open, I wont even keep it in my wallet. It will just sit in a drawer with my passport and SS card.  <response>: If you close it youll lower your credit score because your oldest account, average account length, and avaliable credit will all decrease. Leave it open and just dont use it.
