why is the heart the symbol of love?
When one feels the humane emotion of love, dependent on the person, your brain sends bigger electrical pulses (yes there is electricity in humans) to the heart. Thats why when your with a lover, best friend, or your texted someone you care about, your chest feels heavy. Mostly in the heart region
it may have something to do with the fact that it is really the center of our life- it pumps blood.
and maybe because when we are in love, and then we lose it- that is the place it hurts.
so somebody over the centuries figured it must be the source of those feelings.
because thats where you feel love
Because it's Cupid's target !
