What is LIFE ?

I have read many remarks and comments about this question, have reached concurrwence with two. I hope some one else has to enlighten me further on this. Two most accepted comments about "what is Life?" are:-
1. "LIFE IS A STRORY TOLD BY AN IDIOT" ---------- W. Shekspere
2. " LIFE IS TO LIVE, NOT TO PREPARE FOR IT" --------- Safarchand.
