This is why everyone wants to have sex with a colleague

If you work your ass off at the office day in and day out and you have piles of assignments that make you feel bad, then you're probably not thinking about sex from nine to five.

No. You don't have to. Certainly not if you're already busy. But you might as well take a good look at that coffee machine, because research shows that we all secretly want to have sex with a colleague. So who knows, there might be a guy at that coffee machine who sees you. Who is thinking about sex from nine to five, so to speak. Here's the thing.

At work, you see people every week, every day. Seeing each other often makes you find someone more attractive than they might actually be. Recognition is a nice feeling, seeing someone sitting at the same desk every day, that feels good. That's why most people at work have a soft spot for at least one person. According to psychologists and researchers, we can even find people good-looking and attractive even if we don't find them attractive at first sight. But once we see a photo of that person five times, we think: hey, wait a minute, they are actually quite nice. That's how it works on the work floor too. You see someone a million times, from Monday to Friday, and then after four years you think: well, let's go on a date. It also helps that you already know a lot about someone (where they work, that is) and what type they are. That feels different than dating a stranger, for sure.

By the way, relationships in the workplace are no joke. Because relationships that start at work often end in a marriage. At least 14 percent of all relationships that start at the copier end up living together. How romantic is that, kissing in the elevator and at that out-of-hand Friday afternoon drink.

Big advantage: suddenly those Mondays with those piles of assignments are a lot less annoying. Because through those rose-colored glasses, even updating an Excel sheet is still fun.
