You don’t need to have seen an Australian Rules Football game to appreciate this story. If you understand the term “mates” that’s good enough. Mark Smith, 13, and Jarryd Haines, 12, have always loved playing football and their hometown Sydney Swans. According to The Guardian, Mark was diagnosed with brain and spine cancer at age 9, and had to endure difficult medical treatments.
