  • In an adult human, 25% of their bones are in the feet.
  • The brain will protect itself even if it means misery to you or death. For example, it will make you stop breathing and pass out if you inhale smoke in the middle of a burning house.
  • The lining in a person’s stomach is replaced every 4 to 5 days to prevent it from digesting itself.
  • An adult human’s small intestine is about 18 to 23 feet long, which is about four times as long as an adult is tall.
  • A person’s feet has about 500,000 sweat glands and can produce about a pint of sweat a day.

  • The largest cell in the human body is an egg (or ovum) and is barely visible to the naked eye.
