WHY does the brain consume the most oxygen and calories?

The brain contains up to 60% fat. It is the fattest human organ.

It makes up less than two percent of our body, but consumes about 20-30% of the calories in our food intake. Thus, constant malnutrition has a negative effect on a person's intellectual development.
Also the brain consumes 20% of all the oxygen entering the body.

For normal functioning of the brain, a person must breathe fresh air.
