Carl Hayman: 1000th All Black on being diagnosed with dementia and his new book 'Head On'

Carl Hayman was one of our great All Black props, considered one of the world's best tight-heads. He was the 1000th All Black when he made his debut against Samoa in 2001 and went on to play 45 tests. He turned down future All Blacks contracts to play overseas for the last eight years of his 17 year rugby career with the sole aim of setting him and his family up. But recently it's his off-field battle that we know Carl best for. He became the first All Black of his generation to be diagnosed with early onset dementia - it's all in his book Head On and Carl Hayman joined Mike Hosking.
