Question

Why the number of times a person inhales and exhales is equal?

Answer 1

Toddlers might breathe 20-30 times per minute. 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.
