Love is an interpretation of protein secretions in our brain. This is true and indisputable. In that sense there's nothing magical about what we call "love". We tend to mystify that interpretation because like other extreme emotions - hate and sorrow - love (or that protein secretion) has allowed people to lift heavy objects or run into burning buildings despite what our evolutionary imperative might tell us. It's a great feeling, probably better than all the narcotics in the world if you have the proper stimuli in your environment - a hot chick/dude with which you can connect on an intellectual level, for example - but to attribute peoples' actions based on that feeling as "magical" is absurd.

It's similar with faith and religion. You can believe the earth was created in six days and that God created man from dust, but you'd be wrong according to the evidence. The religious folks will say you're missing the beauty of creation and that science offers a cold reality, but I'd argue the opposite; simple explanations such as, "God did it" or "love conquers all", strip away any of the beauty we as humans can extract from our world. It's confining in its outlook. Love is a protein interpretation for this and this reason (I won't get into the reasons here), doesn't detract one bit from the beauty and really just serves to enhance it because in the minutia of the explanation lies the reason why it makes sense. With the other explanation it would be easy for someone to come along and refute "love" on the grounds that it baseless and something humans made up. The evidence perpetuates the legitimacy.

Love is not special. You're not special. Your significant other is not special. There is nothing mysterious about love and the underdeveloped teenage brain is obviously going to have a different interpretation of that protein secretion than a fully developed adult (usually starting in their mid-twenties with males and a little bit earlier with females), but that doesn't mean we can't find beauty in our relationships with people; it just means there's a reason for those relationships and why we do the things we do for the people in our lives.

Nothing magical about it, dudes.
