Life

Whenever you think, Think Deeply...!
We are given a limited time to spend our lives in this world. What is reality? Assume a person lives sixty years of life. Thirty years of his life he spends in his sleeping. Fifteen years he spends in his childhood activities,and the rest of the time left he spends in earning and spending. How much time he has to spend for his immortal life?
Do we have the time to think about the real life?
We should not waste our precious moments of life in his way.
