The heart is the hardest working muscle in the body. Every day, it creates enough energy to drive a semi-truck over 18 miles. Over a lifetime, that’s equivalent to driving to the moon and back.
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 of skin.
Your brain is always working, and it is actually more active while you’re sleeping. Scientists say the average person has roughly 70,000 thoughts each day.
WOMB WITH A VIEW
Babies in the womb grow 8,000 new brain cells every second. Newborn babies can recognize their mother’s face after just a few hours.
The typical human sneeze travels at just under 40 mph. That’s the same speed as a running tiger!
During an average lifetime, the heart will pump nearly 1.5 million barrels of blood. A
pumping human heart can squirt blood 10 yards.
The brain itself doesn’t have any pain receptors, so it doesn’t feel anything. That is why surgeons can perform open brain procedures on patients while they are awake.
You’re born with more than 300 bones, but by the time you’re an adult, you have just
206. This is because some of the bones fuse together.
Scientists have discovered that the visual cortex of blind people can rewire itself to respond to stimuli received through touch and hearing, helping them to “see“ by touch and sound.
The brain is 60 percent fat, but it still works hard. At any given time, your brain can generate up to 25 watts of power — that’s enough to power a light bulb.
