People are afraid of sharks and planes, but this is the biggest killer in the world.

Social media circulates a video that graphicly describes and compares the annual causes of death from people worldwide.

Data from the World Health Organization, National Geographic, BBC, and other reliable sources clearly shows that what people fear is often not so deadly.

Unlike snakes, sharks, and the likeness of monsters, heart and circulation diseases kill some 18 million people a year, more than any other cause of combined death.

The authors of this video, however, claim that the data is not complete, or that there are other causes of death, but also this sign of “culated” clearly shows what we should fear.
