If you went biology in high school, you know that your brain is made up of different centers that control different parts of your body both mentally and physically so it would come at no surprise that there is an area of the brain that has a "holiday center!"
So what is a "holiday center"?! According to Bustle, there was a study done in Denmark in 2015 that found that different parts of your brain lights up when thinking about special holiday memories, traditions and so forth are brought up and compared to stuff from the rest of the year.
Kind of interesting huh?! It totally makes sense now!
