I have records of 42 cards, and I am 42. I currently have 23 open. Very sad that my very first card (class attractive coed in the union asking freshmen to sign up trick) from Citibank got closed for inactivity. I still have my Discover and another card opened that year.

I wasn't that aware of churning and didn't know about FT until way too late unfortunately. The Citi Amex card I had was by far and way the most points I ever earned on a card, it was insane. Now I primarily use BOA Cards for 5.25% in categories (I have five CR cards so I can get 5.25% on up to $12,500 per quarter) and 2.625% on everything else due to my status with BOA/Merrill. But I just had to renew my Global Entry and realized that the IHG Premium Card covers the $100 - I used my Saph Reserve credit for a friend and recently closed my Prestige, so that was a nice find. Worth a google no doubt.

I also had an American Eagle store card and a Home Depot Card, and an Old Navy card I think at one point haha but didn't count those above. in the above, an Eddie Bauer Master Card, a Gateway Computers Card through MBNA, classics.
