Modern day events like swimming, athletics and much more will also be featured in the games with a 'traditional' twist.One of the most intriguing events will be Xikunahiti, otherwise known as head football, a South American tribal game where competitors play the ball with their heads.The motto for the games are "Em 2015, somos todos indígenas" meaning 'in 2015, we are all indigenous [people]'.One indigenous youth, Dream Braga, has already made Brazil's national archery team after taking part in a program meant to encourage native bowmen to transfer their expertise at shooting fish and other animals to sport.
