Growing skin

Skin is the human body’s largest organ and is constantly renewing itself. Your skin sheds 50,000 cells every minute. Over a lifetime, that piles up to 40 pounds (18.1 kilograms) of skin.

Hard-working heart

The heart is the hardest working muscle in the body. Every day, it creates enough energy to drive a semi-truck over 18 miles (30 kilometers). Over a lifetime, that’s equivalent to driving to the moon and back.

Aging brain

The human brain is the most sophisticated thing in the known universe. Humans have more brain cells at the age of two than at any other point in their lives, but it takes nearly 20 years for the brain to mature.

Pool of drool

An average person produces about 1.8 pints (one liter) of saliva a day or 25,000 quarts (23,658 liters) of saliva in a lifetime. This is enough to fill two swimming pools. 

Color of bones

Did you know the color of the human bones are actually range from beige to light brown? The bones you see in museums are white in color because they have been boiled and cleaned. 

Long-term storage space

Your brain’s long-term memory, which develops until the age of 40, can hold as many as 1 quadrillion (1 million billion) separate bits of information in a lifetime. 

Long arteries

If your arteries, veins and capillaries were laid out end to end, they would measure 62,137 miles (100,000 kilometers). That’s nearly enough to stretch two and a half times around the planet!
