The history of
humankind numbers thousands of decades of continuous development that made
people the way we are now. Hundreds of wars, catastrophes, epidemics and other
factors influenced the formation of human race. In spite of the fact that
modern researchers are trying to do their best in order to unravel all secrets
of the planet Earth, but we haven’t even reached the middle of universal
knowledge. So, don’t be surprised by that fact that there are a lot of
interesting facts about our planet you didn’t know. If you want to widen your
range of vision, go on reading our article. Today, we are going to tell you
something much more interesting then how to get a good haircut

Katzenklavier is an
invention of German scholar, that was made in 17 century. Literally, it means
“cat piano” in German language. It consisted of several cats, with different
voice pitched, caged in a row. Are you interested what made them produce the
sounds? Sharp prick in the tail will make any cat Meow. We should say that it
is absolutely inhumanly and cruel, and thanks God this invention is left far
behind.
# 2 An epidemic of laughter
Do you have a very
infectious laughter? Be careful with it! In 1962 year, in Tanzania started an
epidemic of laughter. It only sounds funny, but in reality, several schools
were closed, and the whole epidemic lasted for about a year! People were
complaining about pain, fainting, rashes and crying, and it is not good at all.
# 3 Blue skin people
Do, you think that
only Avatars have blue skin? No! There was a family, who lived in Kentucky
state for many years and they had a blue skin! Rare genetic disease called
methemoglobinemia made them look like that. Who knows, maybe they served as
prototypes for famous movie everybody loves so much! And would you like to have
blue skin? Is it cool to be different?
Hope these facts were
useful for you and made this day more interesting. Open your mind and enjoy a
wonderful life you have.
