They had 12 other children with other partners, but Leonardo was their sole kid together. Because of his illegitimacy, he was not expected to follow in his father's footsteps and become a notary.

People invented "safety coffins" after being buried alive by accident so many times.
Doctors frequently misdiagnosed sick patients, which was common in 17th century England. Alice Blunden is one such example. After she drank sedatives, a doctor mistakenly declared her dead, and she was buried alive. This terrifying ordeal occurred not once, but twice. After exhuming her and discovering she was near death, they buried her again, only for her to struggle in the casket, still alive, until she died.

Doctor Strange was nearly not given to Benedict Cumberbatch.

While most people add roses to their gardens for their beauty, roses have a long history of being used as food and medicine. Roses are classified as "herbs," and as such, they are considered useful plants. Their petals are edible, and rose water (made by soaking the petals in water) is frequently used to flavor jellies and jams, as well as in Indian and Chinese dishes. Keep in mind that if you're going to eat roses, they should be chemical-free. Use roses that have not been sprayed with pesticides or other chemicals, and avoid using cut roses from a flower shop or supermarket because they have been grown with a variety of chemicals. It is possible to grow your own roses.

An adult rattlesnake typically passes two weeks or so without eating because they only eat when they are hungry. The precise length of time depends on how much they ate for their last meal. Rattlesnakes mainly prey on mice, rats, squirrels, and rabbits, but if they can capture them, they will also consume birds. Young rattlesnakes typically consume more food, up to once a week.

Dord was defined as density in a 1934 edition of Webster's New International Dictionary as a result of spacing confusion. To protect their copyright, some dictionary editors have purposefully included fake words, such as equivalence in The New Oxford American Dictionary.
