How much blood will you heart pump if you live an average lifespan?

I have no idea, thats why im asking the question!!

Well, I've just calculated 720, 000, based on an Olympic swimming pool holding 2500,000 litres (Wikipedia); and one heartbeat pumping 70cm3 of blood at 70 beats/minute, and an average lifetime being 70 years

= 1.8 x 10^11/2.5 x 10^6

= 720000
