Everyone knows the nursery rhyme "Mary Had A Little Lamb," but you probably didn't know this was based on true story. Her name was Mary Sawyer. She was an 11-year-old girl and lived in Boston and one day was followed to school by her pet lamb. In the late 1860s, she helped raise money for an old church by selling wool from the lamb.
Cleopatra Was Not Egyptian - Despite what you may believe, the last queen of Egypt wasn't born in Egypt. As best as Historians can tell, Cleopatra VII (that's her formal name) was Greek. She was a descendant of Alexander the Great's Macedonian general Ptolemy.
During the Renaissance in Venice, noblewomen and courtesans wore special platform shoes, called chopines, that were up to 20 inches tall. As women risked falling down in the street, a law was passed there to limit heels to 3 inches, although shoemakers ignored it. When commoners started wearing heels, their height was regulated according to the status of the wearer: no more than 1/2 an inch for those on the lower end of the social strata!
The first high heels were actually boots. In the 10th century in Persia, they were worn by calvary men who discovered that a tall heel hooked securely around a saddle stirrup and made for easier riding. Those in the midst of battle could hang on to their horses for protection without falling off.
The first heels appeared 400 years ago.

Silver is good for your health - We’ve all heard the phrase “born with a silver spoon in his/her mouth,” and most of us would take that to mean the child grew up wealthy. But did you know that the idiom originated as a way of saying that the person never seems to get sick? Because of silver’s germ-killing properties, in the old days children who were fed with silver spoons (which was a luxury often reserved for wealthier families) were typically healthier babies.
The term Bluetooth comes from a Nordic king
It is about the Danish and Norwegian King of the 10th century, Harald Blatand, wrongly translated into English as Harald Bluetooth. He was known for his speech and conviction skills, this King was able to unify the Norwegian, Swedish and Danish tribes and convert them to Christianity. Another clue to make sure we are right about this: the Bluetooth logo combines the Hagall and Berkana runes, which correspond to Harald Bluetooth’s initials.Mobile phones contain many more bacteria than a toilet flush.
