I did some research on this mystery because I wanted to find out two things: one, to find out if it’s legit and two, who it was discovered by. I was surprised to find that there’s not a lot of information on this topic and most of the information I did find were opinions of very bitter women who blame society on inventing this ridiculous idea.
I finally one article that suggested our body odor that’s created by the genes involved in our immune system, more specially our DNA, is to blame for this phenomenon. According to Tamara Brown, a Croatian geneticist based in Zurich a section of the DNA called human leukocyte antigen plays a key role in searching for "true love" and the key lies in "secret signals" one picks up from anothers body odor. I suppose that this isn’t too far fetched seeing as some males excuse their sexual desires and fear of monogamy on their natural animal instincts so why can’t we propose that our smell is “the spark” that’s going to make Ryan Gosling your husband or Megan Fox, your wife?
If it’s really a natural scent that draws in your soul mate, then why hasn’t this cat been let out of the bag? I would have saved hundreds of dollars on perfume if someone had told me this earlier! In my opinion, feeling “the spark” is legit but it’s not because someone smells good, although I can think of a few instances where I’ve wandered down the body wash isle and secretly taken a sniff of men’s Old Spice (shameful, I know), it’s just one of those things that can’t be explained. Kind of like that dizzy feeling I get when I stare at Channing Tatum and Ryan Gosling for too long. Hey, a girl can dream.
