You got: 31-45!

The fast food scene has changed a lot over the years. In those days when fast food was a novelty, there were only a few options around like McDonald's, KFC, and Domino's. These days the whole scene is different. Even as people are going vegan and trying to eat healthier as a whole, new fast food places are popping up pretty much everywhere you look with places like Chick-fil-A, Panera, and Chipotle. One thing that is clear by now: fast food chains aren't going away anytime soon.

Did you know that your fast food habits can be rather revealing? Researchers have found that as people get older they eat less fast food. Men are more likely to eat fast food at lunch than women, and women are more likely to eat it as a snack.

Do you tend to crave for the Big Mac, or prefer your burgers from another place like In-N-Out? When you get in the mood for fried chicken, would you head to a KFC or Popeyes?
