How many breaths do you take in a lifetime?
At 14 breaths a minute over 73 years, the total is about 540 million; the honest range is roughly 450 to 750 million because resting respiratory rate runs from 12 to 20 in healthy adults and rises sharply with exertion. Each breath moves about half a litre at rest, so a lifetime moves something like 300 million litres of air — around 12 million kilograms. Newborns breathe at 30 to 60 breaths a minute, roughly three times the adult rate, which is why a lifetime average is not the same as an adult average.
How the figure is arrived at
14 breaths/min × 60 × 24 × 365.25 × 73 = 537 million. The same arithmetic as the heartbeat figure with a different rate, and the same sensitivity: the range in normal respiratory rate is wider proportionally than for heart rate, so the answer is less precise.
