The tenth President of the United States, John Tyler, served as the President from 1841 to 1845. He was born in the 18th century and died in the middle of the 19th century.

Five of the children from his second wife lived in the 20th century. One of his son, Lyon Gardiner Tyler, had 6 children from two marriages. His last three children were born when his age was more than 70.

14. The deadliest animal on earth are mosquitoes with more deaths attached to them every year than any other animal in the world.
When asked about the most dangerous animal, most people would say sharks, lions, snakes or any other animal. But the reality is different. Every year, there are more deaths due to mosquitoes than any other animal in the world. This is because mosquitoes are the carrier of dangerous diseases like malaria, yellow fever, chikungunya, encephalitis, dengue fever, and others. It is estimated that more than 600,000 people die each year due to malaria. Also, except for Antarctica, mosquitoes are found all over the world. This means it is a huge threat to people throughout the world.(source)
15. There’s only 1 pig in Afghanistan, and he’s in a zoo.
It’s true. There is only one pig in Afghanistan, and its name is Khanzir. He is 14 years old and lives in Kabul Zoo. The reason behind Khanzir being the only pig in Afghanistan is that Afghanistan like most Islamic nations believe eating pork is considered such a sin that even touching them is forbidden.
But Khanzir hadn’t always been a lonely pig. He was sent from China in 2002 as a piglet along with a female pig. They both mated and even had a litter of piglets. But in 2006, a caretaker left the nearby bear’s cage open and one of the bears managed to enter the pig enclosure. It killed all its piglets and gravely injured the female who later died due to the injury. So, Khanzir is left all alone now.(source)
16. The amount of time between Stegosaurus and Tyrannosaurus is more than the amount of time between Tyrannosaurus and us.
Stegosaurus roamed western North America about 150 million years ago while the Tyrannosaurus evolved only 67 million years ago. So, the difference between the evolution of stegosaurus and Tyrannosaurus is 83 million years which is far greater than the difference between us and Tyrannosaurus i.e. 67 million years.(source)
17. The youngest mother in history was 5 years old!
Lina Medina became the youngest mother in the world when she gave birth to a boy at the age of five years seven months 21 days. She was born on September 23, 1933, in Peru.

She named him Gerardo after her doctor. Gerardo was raised believing Medina was her sister. He came to know about their real relation at the age of 10. He died at the age of 40.
Lina is currently living in Lima. So far, she hasn’t confirmed the identity of the father of her child or the circumstances surrounding her impregnation.(source)
18. It rains diamonds on Saturn and Jupiter.
The US scientists have calculated that diamond rain could be a very common phenomenon on Saturn and Jupiter. It is estimated that diamonds as big as one centimeter in diameter is falling on these planets regularly. Consequently, about 1,000 tons of diamonds are fallen on Saturn every year.
Lightning storms on the surface of these planets convert methane into soot (carbon). The soot hardens when it falls, and it forms chunks of graphite. Eventually, it turns into chunks of diamond due to the extreme temperature and pressure. The diamonds then rain on the surface of these planets and finally melt into the liquid sea of the planet’s super-hot core.(source)
