Breathe* and breaths* for starters.

We only breathe in what our body feels is necessary. Every time we breath we still end up exhaling a lot of the oxygen we had just breathed in. If you try to breathe more than you need to your body will go into an O2 overload state where you will start to feel funky.

There’s more to it like what happens with your blood but since this question is strictly about breathing I’ll leave it at that.
