A child is a man as it is proved before your eyes.

Can you think that it is the reality that we bear, grow, become young, face difficulties of life and at the end, become old and helpless instead of not having like. Just think and ponder over yourself, why you are here in this world and what your responsibilities in life and what Will happen next.
I think these are not simple questions and everyone wants to know them clearly. So think about the mission of your life once a day.
