The human brain operates on about 20 watts of powerβenough to light up a small bulb. This electrical activity is a result of neurons firing signals to communicate with each other, enabling everything from thoughts to movements.

The average human heart beats approximately 100,000 times a day, pumping blood through 60,000 miles of blood vessels. Over a lifetime, this relentless organ contracts over 3 billion times without ever pausing to rest.

For every human cell in your body, there are about 10 microbial cells. These bacteria, viruses, and fungi, collectively called the microbiome, play crucial roles in digestion, immunity, and even mental health.

To protect itself from being digested by its own acid, the stomach regenerates its lining every 3-4 days. This acid is strong enough to dissolve metal but is perfectly contained within the stomach's protective walls.

Ounce for ounce, human bones are stronger than steel. A cubic inch of bone can bear loads of over 17,000 pounds, making it one of the toughest materials in the body despite its lightness.

The liver is the only organ in the human body capable of regeneration. Even if up to 75% of it is removed, it can regrow to its original size within weeks, provided the remaining tissue is healthy.

The outer layer of your skin, called the epidermis, is constantly renewing itself. Every minute, your body sheds around 50,000 dead skin cells, amounting to about 1.5 pounds per year.

The human eye is equipped with millions of photoreceptor cells, called cones, which allow us to perceive a vast spectrum of colors. Some individuals, known as tetrachromats, may even see additional hues beyond the typical range.
