the complexity of love

My favorite and most complex subject would have to be love. I chose this topic not because i have experienced it but because lives revolve around it. Love is an emotion that no scientist can manipulate and it is a main goal that the human race seeks. love is not something that you can pass a class to obtain, it is not something that money can buy and noone knows whether they will ever experience it. This is something that bewilders me because if love is so complex then why does the human race desire it in such a way? Most people only believe in things that they can identify with the five senses, things that dont fail them and consist of little to no mistakes. Love defies all of these human aspects and yet nomatter where you go if you mention the word love it will not come off as a forign language. This is why love is so interesting to me because it can not be controlled or tamed it is one of the WORLDS biggests challenges.
