There are the rushes of ecstacy, the gut wrenching anticipation, fluttering, dizziness, and the diminished concentration that turns day-dreaming into a full-time job. And then there are the side effects. A positively Colombian annihilation of appetite and its confidence- boosting by-product, weight loss. But no one knows what "it" is.

There are, in fact, three distinct stages of love; each with their own characteristic emotional profile and scientific explanation. First is lust. Lust is driven by our sex hormones testosterone and oestrogen. These hormones are what get us 'out on the pull'. After lust comes attraction.

yup. i've studied psychology - and i'm not quite sure what the name of the chemical is - but there's definatly a chemical released when we find someone attractive - i think it might be adrenaline - but i'm not sure - it's been a while since i studied relationships lol.

A chemical called dopamine is released when we are around someone we find visually or mentally pleasant or stimulating, which teaches us being with that person is an enjoyable experience.

Yes there is a chemical reaction caused by the brain cells... It is the passion that we feel when we see someone really attractive...

Pheromones...
