Old vs Young is a tribe division twist which divides the tribes based on their age.
In most cases, both the younger and older tribes have suffered with camp life and delegation that has resulted in numerous factions and counter-alliances being created, typically led by a more devious contestant.
The contestants were split into four tribes to begin the game: La Mina (older men), Casaya (older women), Viveros (younger men), and Bayoneta (younger women). This initial separation lasted only one episode, as the four tribes became two (La Mina and Casaya) on Day 4 after a Schoolyard Pick. This season featured one representative from each of the original tribes in the final four: Cirie Fields for Casaya, Terry Deitz for La Mina, Danielle DiLorenzo for Bayoneta, and Aras Baskauskas, the eventual winner, for Viveros.
The twist returned in Survivor: Nicaragua; however, the tribes were only split based on age rather than age and gender as previously seen in Panama. La Flor was the "younger" tribe, consisting of contestants 30 years or younger. Espada was the "older" tribe, consisting of contestants 40 or over. On Day 12, both tribes took part in a switch, thus dissolving the "old vs. young" twist. This season featured a Final Tribal Council made up of three members of the original "young" tribe, La Flor: Sash Lenahan, Chase Rice, and Fabio Birza. Birza went on to defeat Rice and Lenahan 5-4-0, respectively.
