25,550 Days

I'm reading the "Purpose Driven Life" again and in the first chapter it says that the average person lives 25,550 days (70 years) I checked a life expectancy calculator on MSN and I added 5 years to bring the total to 75 years or 27,375 days. According to my calculations I have just under 10,000 days left (9880) I am really going to start making the most of them.
