What the hell it love?

what is love? is it only a word? composed of letters, disguising an emotion? so what is it really? besides four letters the word that is so hollow yet sound so full it has more of a use then a description people use it to describe something they supposedly feel something straight from the heart but how can it be from there it only pumps blood love is supposed to be red blood is so when we bleed are we losing love or life no love can't come from the heart it is a sickness of the mind its one of the names we give to something to blame our problems on people kill for love spilling blood people die for love spilling more blood people live for love keeping all the blood they have people hide from love fearing red people give love exposing there true colors or giving thier blood people take it adding more to what they might lose people use it flatly apparently it confuses them that is why they made the word.
