How Many Breaths Does A Person Have In A Life Time?

It really depends upon how long a person lives and how much exercise they do during their lifetime. Also, young children have a higher respiratory rate than adults do.

However, a person at rest with a respiratory rate of 16 breaths per minute - which would mean they never exercised - and assuming they lived until eighty years of age, would breathe almost 700 million times in their lifetime.

This is by no means accurate.
