<prompt> Human: Years ago I started out with a credit limit of about 2000 usd. I was probably about 20 or so. Now Im 27 and its been raised incrementally over the years to 5500 usd. I dont need or use this and I havent spent anything close to my limit I probably put 5-600 a month on it and then mostly pay it off. I also have never gotten another credit card because the limit so high. This seems like a good thing, but Im not sure and I havent really paid much attention to it. I dont make a ton of money and live with my parents to keep costs low. It just seems odd to me that I have this limit. Should I do anything?  <response>: Its a good thing. Dont worry about it. I have basically lost count of my total credit line. Last audit of my cards I was around 100k in available credit
