From birth, Gregor is deaf in one ear. Being deaf is unfortunately still a taboo subject. Gregor wants to show with his charity work that you can achieve everything and don't have to be ashamed. A certain area in Gregor's brain is underactivated and he now has to compensate for this. His balance system and eye movements are essential for ski jumping. Despite all this, Gregor won 53 World Cup victories and 4 Olympic medals.
