Time is a valuable thing which goes on continuously from past to present and present to past. There is a huge development in science and technology but none of the person (scientist) have invented such thing which can stop the time. But it can be said as there is some try made by some of the scientist which have invented the machines in order to measure the time.

Time can also be said as the most powerful thing in the world. It can give a life as a small baby and a death which is not only for an old man but also for a baby or other stage of human life. It can changes the state of human, from a baby to child, child to adult, an adult to old man.

A poet named "W.B Yeats" has included the negative aspects of time in his poem "The Lamentation of Pensioner" because it changes all his day from happy and joyous into the life of sorrow. He has also said that he want to spit into the face of time. How ever the time may be powerful but it cannot steal all his happy memory. So, in this context, he himself thinks superior than the time.
