− | The age of a creature has an important effect on its overall [[size]] | + | The age of a creature has an important effect on its overall [[size]], as most creatures are not born adults. The starkest example of this in the game is the case of the [[dragon]], which is born 6,000 cm<sup>3</sup> in size and takes a thousand years to mature to full adulthood at 25,000,000 cm<sup>3</sup>. However, the vast majority of the non-sapient creatures your dwarves encounter take only a year to mature to adulthood; [[elephant]]s and [[giraffe]]s are a notable exception, as their young take ten years to mature. All non-sapient creatures that have not yet reached adulthood have a "baby" moniker attached to their species name. [[Savage|Giant]] versions of animals inherit their normally-sized brethrens' lifespans, while [[animal people]] usually have somewhat longer lifespans than their representative creatures. |
− | The life cycle of [[dwarves]] is slightly more complicated: juveniles ages zero to one are considered babes, and must be carried about by their mothers; between the ages of one to twelve are they are considered [[children]], and can perform some limited tasks; and once they reach 12 years of age, they are considered adults.

The process is the same for other [[creature#civilized|civilized]] races, [[animal people]], and the humanoid [[semi-megabeast]]s. |

Most organic creatures will eventually die of old age (including fortuitous fortress dwarves), but a few, such as [[elf|elves]], [[goblin]]s, and some unintelligent and unnatural creatures, will live until killed. [[Megabeast]]s, the [[undead]], [[night creature]]s, and the procedurally generated [[forgotten beast]]s and [[titan]]s are similarly immortal. Immigrants may sometimes show up with incorrect ages (future birthdates) {{Bug|3945}} or incorrect life stages (4 month old children) {{Bug|3752}}. This normally does not cause a problem, and life stages get rechecked every birthday. Note that only an intelligent civilized creature vulnerable to death by expiration will seek [[necromancer|necromancy]], which means goblins and elves never become practitioners of the dark arts. |

− | The mechanics of aging are defined | + | The mechanics of aging are defined within creatures' [[raw file]]s, and can easily be modified by those looking to make changes to their game. |
− | * | + | *<tt>[CHILD:#]</tt>: Age at which children become adults. 1 for most creatures, 10 for a few others ([[giraffe]], [[elephant]]) 12 for sapient creatures, 1000 for [[dragon]]s. |
− | * | + | *<tt>[BABY:#]</tt>: For sapient creatures, age at which babies become [[children]]. Always set to 1. |
− | * | + | *<tt>[BODY_SIZE:#:#:#]</tt>: Controls the body size of the creature, typically two or more are used to constrain its growth pattern. The tag is interpreted by age; strangely the second parameter always appears to be set to zero. The third number is its size in cm<sup>3</sup>. The age points may be larger than the age of adulthood for the animal: for instance, according to their tags deers double in size between one and two years of age. |
− | * | + | *<tt>[MAXAGE:#:#]</tt>: The first number given is the minimum natural lifespan of a creature, while the second is the maximum. The distribution of deaths from natural causes in between the two values is unknown, but likely linear; interestingly, receiving even the most severe of non-lethal [[wound]]s has no effect on a creature's lifespan. If this tag is not present at all, the creature is biologically immortal. |
