Why do we forget?

We do almost all vertebrates at one time or another, but it is still not clear why we do it.

We especially yawn when we are asleep or when we are hungry, and the possible explanations are two: According to a theory, in these situations of drowsiness or hunger breathing is slower and the levels of carbon dioxide in blood increase. And the yawn is the involuntary mechanism we use to raise the level of oxygen in the blood.

However, others consider that the yawn is, therefore, the mechanism we use to capture the attention of others. Or the mechanism to maintain inflated lung bags.

And when we're inside the egg count, why is it contaminating? If the theory of the lack of oxygen is accepted, it seems unbelievable that we all at the same time have a lack of oxygen, but if in a room there is a group of people, it is possible that carbon dioxide accumulates and a collective need to yawn is generated, and if we lack oxygen, we also lack who is next to it.
