What is love?

Na...I am not researching on this particular subject, but believe me; if anybody has guts to do to...Then seriously hats off to him...Come on!!!!

I tell you what love is....’It is that hyper activity state created by the combination of your mind and body, where brain doesn’t seek logic and heart doesn’t mind speed...Once you fall in the gravity less valley of love, there is no coming back..By gravity less I meant, that amazingly enormous pit where even though you have fallen, still you feel, you are on the top of the world...It has the tendency to cut you in pieces and still you are content about it..It may make you warm and cold at the same time...Cries and laughs, at the same instant...But the fact remains the same, however bad or good your day is, still you have a person out there whom you love passionately, sincerely and heart stoppingly, wishing every moment of your life that how special you would feel, if you received the same amount of love back...
Love is that emotion, that seems bigger than anything else in this world...Be it exams, assignments, friends, or whatever...You may call it a cancer increasing at an exponential rate, increases still, with every phone call you make, with every moment you share and with every smile you get..For you that person, matters the most, to an extent that with every good word spoken is your cherished memory and every fight you make is a bad dream...There is this line which I really liked, when I first time read it in a book.."I am not mad in love...But I love her madly...”Obviously the author was a guy...
In love, you want to hug him and want to look into his eyes and say "I love you", cry for him and still want to show him your tears, laugh at him and still say you are not stupid, get angry with him on text messages but when you hear his voice, all your anger is washed down the drain..You tend to walk, with every morsel of fear, thinking what would happen if he stopped talking to you or what it would be like of not having him in your life?
Love is, when you start hating that very girl of whom he ever talks about...And despise every guy who is a competition to him...He is flawless for you, even though he is human..And with every mistake he makes, you love him many times more...It is that feeling that gives immense amount of pain, but still you feel happy receiving it..'
I think my explanation is like a summarised answer written on an answer sheet, that answer of which you are totally unsure about... Hope it gives you a clear idea (but it hasn’t to me) whether LOVE is a notion, creation, emotion or crime??
So tell me what exactly is love???
Waiting for your answers...
