Rugby damaged my brain
There has been serious attention paid to concussion in sport recently.
Rugby has received a lot of this attention in New Zealand.
As the game has evolved the athletes have become larger, stronger and faster. I would estimate that professional athletes are now at least 10kg bigger than when I entered the professional game in 1996. Rule amendments have resulted in the game becoming faster and the contact intensity has magnified.
The recent focus on concussion within sport has brought much needed attention to an injury that struggles to be understood.
Concussion is an invisible injury. The effects can be varied and it's difficult to understand.
