Answer

About 22,000 breaths

Your two lungs are not the same size. The left one is smaller to leave room for the heart.

How to estimate it

Time your own breathing: a resting adult takes about 15 breaths a minute, a little less in sleep and more during effort, so 15 is a fair average. A day has 24 × 60 = 1,440 minutes. 15 × 1,440 = 21,600 breaths. The commonly quoted figure is about 22,000 breaths per day.
