Is there a love chemical ?

love is critical to the continuation of our species, without it we would live in  society that resembles the animal world. There are chemicals that race around in our brain when we're in love, chemicals that make us want to form families and have children. Once we have children, those chemicals change to encourage us to stay together to raise those children.

yes there groupe of chemicals called feromones!

Imagine an invisible, undetectable force that's powerful

I hate to bust your bubble, folks, but you are talking about aphrodesiacs.  Science and psychology have confirmed experimentally that there is no such chemical.

However, if you want a girl to fall madly in love with you, certain carbon structures will usually do the trick.

They are easily commercially available at any well run shopping center.

I refer to a beautiful bouquet of flowers, a box of chocolates, gradually increasing the romance of your nights on the town to about eight per week, then finally a contrite look, a little chip of diamond on a ring her size and a gentle kiss.

That's the best love stimulant I ever used.  That was 26 years ago, and I still bring her home flowers.

Works like a charm!
