Who would have ever guessed that men and women would be attracted to each other due to their scents and symmetry of their bodies? It always made sense that humans have common traits with other mammals, it just was not something I thought would be similar. We have weaker senses opposed to other mammals so it did not seem like something we would have in common. I did not think we would use our unconscious scent in determining our moods and reactions to situations. Also, I not think that the symmetry between two individual's wrists would make any type of difference in whether or not they feel chemistry towards each other.
