False history

 There are many histories that we consider them real but they aren´t. For example, we say that Einstein wasn´t good at maths and he failed. This is false because they evaluated from 1 to 5 and a 1 was the best mark that a student could achieve. I have been looking on internet and I have discovered many things like this. The strangler of Boston was a famous murderer that killed 13 people and we call him like this because we thought that he strangler everybody but he only strangled his first victim, the rest were stabbled.

 This history doesn´t change much our daily lifes but some of them yes. For instance, there is a lot of people that think that the VIH isn´t real and they deny it as an illness.
