Let's face it: Being cheated on is probably the worst feeling ever.
And according to a new AsapSCIENCE video, it may have something to do with how our brains are wired.
Here's where the science comes in. It has to do with the gene coding for a dopamine receptor, or the "happy" chemical that's released in our brains when do "pleasurable" things, like eating a delicious meal and having sex, to name a few.
Upon taking a closer look at this, researchers found people who have a long allele for this receptor are more likely to love taking risks (hello, skydivers), struggle with addiction and -- drum roll -- cheat.
There are other factors that go into cheating, of course, and we don't want to give the whole video away.
Cheaters may also be more likely to cheat again because they get a "cheater's high" out of the deal. We'll stick with a runner's high, thank you very much.
