How much did the old man have to pay to his GOD ?

A 70-year-old man had a breakdown And rushed to the hospital and was given oxygen for 24 hours to keep his breath ... And after a period became better and brought him Dr. Invoice was $ 500 As soon as the man saw the bill, he cried out loud The doctor said to him: Do not scream at the value of the bill can be paid by installments Individual man: I do not cry from the amount of the bill I can pay cash I'm crying because I'm just using oxygen for 24 hours and I'll pay $ 500 I stayed for 70 years and I breathe God's air for free now if I am asked to pay. Did you know I owe you my God

Now go back to my calculations again You breathe the air of God for free and at no cost throughout these years.
