What interesting is the history of yo-yo, I never thought that was so remote its origin, although once I heard that in ancient China they used to fight a sort of weapon that had a similar shape to yo-yo, the edges of the discs were sharp as razors. As a child I was very clumsy to handle the yo-yo, in fact, I never learned to use it. There were children in my neighborhood who had the skillfulness for using it. Well one can not know everything in life
