Getting older

*The sun is running on its way.
The earth is moving forwards on its orbit.

*The moon is going around the earth-planet.
The watch is proceeding on its duty.

*All above are working their own functions.
But, we are counting their functions,
such as one day, two days, one month, two months,
one year, two years and so on.

*Our life is also following after their functions.
By this way, we are getting older and older.
