Only Six Months

Beloved Prophet (PBUH) said that the average age of my Generation is between sixty and seventy years. Two friends are talking to each other. If you say your Prayers and avoid sins then you are a complete worshiper. That is your whole life will be counted as a life of worship and obedience. Actual Prayer time for a life time comes out to be around six months. That is all. Anyway one third of life is spent is sleeping. If we indulge in healthy entertainment apart from our work then combined with the fact that lots of our time is spend in education then we realize that the time left to commit sins is rather small. How do we manage to destroy ourselves by committing sins in such a brief time?
