We knew that we are all going to be there someday. No matter what we do, what we have or what we are. At the end of the day we are going to our destination, where we are 6 feet under the ground. No one can't deny and no one can stop that. We never knew when it was. That's why we need to enjoy every thing and each of our time while we are here and still breathing, because we can't said how long we can live in this wonderful planet.
This is the saddest reality of our life, but we should accept this mere fact and believe in life after our life here in earth.
We should learn to appreciate all of those things we have and never focus ourselves in those material things, because after life, it has no value. Always life our life in its fullest and always have fun.
