From the article: "The big kids quickly learned to punch the little ones in the face and take their stuff. Elon, who was small and emotionally awkward, got beaten up twice. He would end up losing ten pounds.

The second time Elon went to veldskool, he was about to turn sixteen. He had gotten much bigger, bursting up to six feet with a bearlike frame, and had learned some judo. So veldskool wasn't so bad. "I realized by then that if someone bullied me, I could punch them very hard in the nose, and then they wouldn't bully me again..."

The story was revealed in the recently released book: "Elon Musk" by Walter Isaacson
