If you assume the average human lifespan is 75 years, then it translates to be approximately 28,000 days long. Older children and adults, when resting, usually breathe about 12 - 20 times per minute. Over the course of a day, that adds up to 17,000-30,000 breaths per day — or more! Those average breathing rates are for when you're at rest. When you exercise — or even walk around the house or school — your breathing rate goes up.

If we multiply our average number of days with our average 🔢 of breath then we get an approximate answer.
