1. It is impossible to multitask.
In reality, we are context-switching while we believe we are multitasking. That is, instead of completing multiple activities at once, we are hopping back and forth between them quickly. According to the book Brain Rules, "multitasking" can be harmful. According to research, you make 50% more mistakes and complete tasks in twice as much time.
2. An adult brain typically weighs three pounds.
Just 2% of a person's body weight is made up of the brain, with the cerebrum accounting for 85% of the total weight. The brain has a solid jelly-like feel. A typical human brain weighed 4.43 pounds at its heaviest. Ivan Turgenev, a Russian writer, owned it. And a woman had the tiniest brain—a mere 2.41 pounds.
3. The brain is composed of water in about 75% of cases.
This indicates that brain processes may be negatively impacted by dehydration, even at levels as low as 2%. Acute changes in memory and attention can result from dehydration, as well as a loss of salt and electrolytes. Make sure your body gets the right amount of moisture to avoid any loss of bodily or mental function.
4. During the first year of life, the size of the human brain triples.
A two-year-old baby's brain will be 80% developed. It will keep expanding till you're around eighteen. Approximately 25 years of age is when the human brain reaches complete development. Compared to other vertebrates, the human brain is the largest in terms of body size.

A group of scientists found that perspiring can result in dehydration, which can impair brain function generally and cause brain tissue to shrink.

In the hippocampus, a part of the brain crucial to memory and learning, this effect is most pronounced. But fear not—it is merely transitory. Everything will be OK as long as you replace the lost fluids.
The average brain is composed primarily of water and weighs about 1.3 kg. It makes up as much as 73% of the brain's mass!
The electricity produced by your brain is sufficient to run a little lightbulb. In other words, about 12 to 25 watts of power. The more than 86 billion neurons in the human brain constantly interact with one another to form a complex network. However, you guessed it—electricity—is the source of everything you see, engage with, think, speak, and even dream. Isn't that shocking?
