dont believe it...

Makes sense actually. Brain tells the eyes to let in more light so you get a better image of whatever you are attracted to.

i dont believe it too... "What has been seen can't be unseen" xD

Actualy it's very true! Its a good sign to know if a perticular girl likes you

maybe, but these images were photoshoped

Old news. Here is something "new": scent is the most important factor, when choosing a good sexual partner. It tells to us subconsciously, if the opposite partner has immune system that is different of yours. The more different it is, the better your offspring's overall health will be.
Also, try this: if you are attracted to some woman and you work or spend time with her, you can tell when she's ovulating if you just follow your body's reactions. That is, if you get a raging stiffy and she looks even hotter than usually, bingo. Your nose tells you what's going in her body.
We truly are just a dressed up monkeys :)

it happens when i switch on the lights in the morning!

Haha this gives me a good reason to look into the eyes of the guy I like...
