Hello!!

The carbon atoms in our bodies no longer exhale carbon dioxide, so it will be many years before they return to the atmosphere as carbon dioxide. Of course, as we pass away, a slew of new babies begin to breathe.

What do you want to tell,it's opposite.
CO₂ is developed during the whole life, if food is consumed and oxidised by oxygen in our bodies.
If dead then first no CO₂ is developed, later some by the decomposition process of the body.
