The science of attraction

We like to think of romantic feelings as spontaneous and indescribable things that come from the heart.

But it's actually your brain running a complex series of calculations within a matter of seconds

that's responsible for determining attraction. Doesn't sound quite as poetic, does it?

But just because the calculations are happening in your brain doesn't mean those warm, fuzzy feelings are all in your head.

In fact, all five of your senses play a role, each able to vote for, or veto, a budding attraction.

The eyes are the first components in attraction. Many visual beauty standards vary between cultures and eras,

and signs of youth, fertility and good health, such as long lustrous hair,

or smooth, scar-free skin, are almost always in demand

because they're associated with reproductive fitness. And when the eyes spot something they like,

our instinct is to move closer so the other senses can investigate.
