Did you know that if the entire human blood vessel system were to be stretched out, it would circumnavigate the Earth two and a half times? In other words, it would be a distance of about sixty thousand miles. Furthermore, in a single day, the blood travels about twelve thousand miles around the human body. That in perspective is close to traveling half the distance of the Earth’s circumference.
A human adult is made up of a phenomenal 7,000,000,000,000,000,000,000,000,000 (7-octillion) atoms. If you want to know how big this is, you have to view it in a different perspective, i.e., there are only about 300,000,000,000 (300 billion) stars in the galaxy. The human body produces approximately twenty five million new cells per second. Within a span of about 14 seconds, the body produces more cells than the population of the United States. Incidentally, the atoms that make up the human body are the same atoms that were formed during the Big Bang, over 13 billion years ago.
The human hair is very strong. In fact, a single strand of human hair could hold 100 grams in weight. The human head contains anywhere between 100,000 to 150,000 strands of hair. Hence, theoretically, the combined hair of a whole head would be able to support 12,000 kilos or 12 tons. In other words, the weight of two elephants. If you were take it weight for weight, it is not as strong as steel, but more like aluminum or Kevlar, that is used for bulletproof vests.
The human bones make up close to fourteen percent of an average human’s weight. Despite that, they are strong as granite. To be specific, a block of bone, the size of a matchbox can support close to nine tons, which is four times more stronger than concrete.
