Love -- it's nothing new. It's the most primal act of nature to ever exist, a tradition that comes from our ancestors just like we do.
It's also the equivalent of your brain being strung out on coke.
It's why when you are in love your brain literally lowers the responses to pain and makes you appreciate the world around you that much more. It even triggers the OCD center of your brain, making you addicted to your significant other.
And while science still knows very little about how love works, ASAP Science does its best to explain why finding that special someone makes you see rainbows and unicorns skipping in green meadows.
