Something related to the shape of the sphere amazed me... I was watching an Aikido video, and this young man in a traditional dress grabbed the head of a man (he seemed to be a master) who was around 60 years old. The master grunted "Hmph!" and shook his head in a spherical motion. The young man flew approximately 2 meters into the air. It makes you think he just jumped on purpose, since he was thrown so easily. But I don't think it was fake, since the video cost over 10,000 yen. I'd like to be thrown once (onto somewhere soft).
