It is known since antiquity that cutting off air supply to the brain results in death. it is also known that glycolysis occurs in brain cells. can glycolysis support brain cells without oxygen?

Glycolysis is dependent on oxygen, as oxygen molecules are necessary to break down the glucose molecule, the target of glycolysis. When an air supply is cut off, Oxygen is cut off as well. Thus, glycolysis cannot support brain cells without oxygen, as without oxygen, glycolysis does not occur and cannot be catalyzed in a normal environment.

Iwould say overuse ( but not 100% sure ) in the u.s. we tend to overuse water by leaving it running, throwing it away, taking long showers, etc.
