I don't think any of us knew the dangers of repeated concussions or the fact that even when you got a concussion, the idea to go get treatment for it never entered our minds. We just didn't have - we weren't educated enough. We were really ignorant to it. I would get concussions in my early 20s racing, and it was a bit of a badge of honor.
Someone like Shane Warne played the game on and off the field really well and got into guys' heads. Even though he couldn't bounce you and hurt you physically, he was verbally aggressive and would let you know he'd get you out. He made batsmen doubt themselves. I learned from players like him and made a point of incorporating it into my own game.
