The average human breathes 13-15 times a minute or 21,000-21600 times in a 24 hour day.
21,600 breaths per day = 7,884,000 breaths per year
7,884,000 breaths per year = 946,080,000 breaths in 120 years or the life span of a healthy human according to yogic texts.

The yogi measures a life not by years but rather by the number of breaths one is allotted to each lifetime.Logic suggests then to slow it down, and make each breath longer if one wants to live longer. In this way we actually conserve energy and increase our vitality and increase our chances of experiencing bliss.

“Breath is mind in action……
The implication of this technology is that we are not helpless victims of a given emotional state.
By altering the flow of nasal breath, the body chemistry gradually changes and unwanted emotional and physiological states slowly disappear”
Harish Johari, author of Breath, Mind and Consciousness.
