We’ve officially entered June wedding fever with the conclusion of the #PaulTin wedding last night. With everybody getting hitched left and right, there’s a feeling of uncertainty and anxiety in the air. This feeling will be familiar to any bride or groom at the onset of their marriage, especially on their wedding day. And who can blame them? It’s the one night that has to lead to their happily ever after.

In 2015, things are moving forward. We’ve ushered in the era of convenience and instant gratification with smartphones and omnipresent WiFi. And yet, for all our advanced ways, we find ourselves still turning to completely baseless and unscientific rituals we call superstitions.

Psychology says it’s the uncertainty hypothesis that has us turning to these quirks. When we are not sure about the way something is going to go, we try to find ways to control them, and to us, apparently, we try to do that by wearing our lucky underwear. Among other things.

It makes sense that our anxiety has bred many superstitions across the globe. One’s marriage is instrumental to your quality of life, and trying to find peace of mind is only normal. While it really boils down to finding the right partner and having the stamina and patience work on your marriage every day (especially when things get rough), we can hope that a happy marriage is as easy as wearing something old, something borrowed, and something blue.

Some cultures have pretty unique superstitions that make you wonder how they came about in the first place, but they all go to show how badly people want their marriages to last. And hey, a little silliness for your peace of mind shouldn’t hurt, right?
