Old vs. Young

 is a game-shifting paradigm employed at the start of a competition that divides the men and women into age-specific tribes for a pre-determined amount of time.

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.

Similar to Battle of the Sexes, men have achieved more success with this twist.

Panama
There were four tribes, La Mina and Casaya were the older tribes whilst Viveros and Bayoneta were the younger tribes. Despite the different divisions on age, on Day 4 the remaining fifteen formed two new tribes either as Casaya or La Mina.

Nicaragua
In Nicaragua, La Flor was deemed the younger group as all their members were 30 years old or younger and Espada was the older tribe as all their members were 40 or over. On Day 12, both tribes took part in a switch.

Reception
Fans responded mildly to this division as the first inception of the twist was between four different groups as opposed to the division in Nicaragua

Trivia

 * Every season that there is a Older vs. Younger twist, the younger tribe(s) always inhabites the final 2/3.
 * The last older tribemember is eliminated on Day 38.
