Why do we not breathe back in the CO2 we just breathed out?

We don’t breathe out with much force, and even if we did, we immediately inhale. So, how do we not just inhale what we just exhaled?

You got the answer from others but i’ll ask a similar: so if you wait after exhale to inhale (slowly breath) you get more oxygen and thats why it makes you calmer?
