The brain is mostly composed of which substance?
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.
Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells.

Brain made of 60% fat so how can it be ‘mostly water’?

What the brain does for the human organism is strong evidence that it could not have evolved over long periods of time. Any significant time lapse between life and mental functioning would have doomed the race to extinction. The brain is one more evidence of the psalmists statement, "I will praise Thee for I am fearfully and wonderfully made!"
