How much air does the average person consume in a lifetime?

Take 500mL of air, multiplied by 15 breaths per minute, multiplied by 41,550,840 minutes in a lifetime and you get a total volume of 311,631,300,000mL of air consumed in a lifetime. Convert that to cubic feet, and you get an answer of 11,005,155.5 cubic feet of air consumed by a human living for 79 years.
