Spawning
How you spawn in the tribe differs and it depends on how many players are already in the tribe.
When you are the first player to start in the tribe, you will be either an adult female or an adult male. The age is 18. If the first players is a female, then the second player will be a male, and vice versa.
When there are already two players in the tribe, and one of them is a female under 50 years old, you will spawn as a baby, either female or male. Babies cannot do anything much rather than moving, and need breastfed by mother or can eat baby food that is given by adults. Their lives depend on the adults around until they become 3 years old.
Lifespan
Basically a player lives until 50 years old but it can be extended by a power-up called "Longevity Power-Up". By eating certain type of food, your lifespan will be extended. For more details, read: Yourself#Longevity Power-Up
Age Differences
Health, hunger rate and stamina are different depending on how old the player is. While you are a kid, all the status bars are shorter so that you need to care more about maintaining your health. Also, you cannot create or disassemble the items that require a large amount of stamina until you become a grown-up.
