Lifespan

Lifespan is the length of a Sim's age in each life stage, which also depends on their life state. 
==The Sims==
In The Sims a baby will turn into a child after 74 hours. This is the only finite Lifespans, as the others do not age and will not die of old age.
==The Sims 2==
The Sims 2 is the first game to feature lifespans. All life stage ages/age ranges are fixed and cannot be modified through the game's settings.
Baby	Toddler	Child	Teen 	Young adult 	Adult	Elder
3 	4 	8 	up to 15	until sim leaves the college sub-neighborhood	29 	range of 9-30 days
Certain life states in the game experience different lifespans to regular Sims: 
* Servos are always in the Adult life stage and will never age.
* Zombies and Vampires do not age, with the exception of teenagers going to college or graduating. In this situation, they will age up to the next life stage but will not age any further when they become an adult. 
* PlantSims only have three life stages: toddler, adult, and elder, giving them a reduced lifespan overall compared to other Sims. However, when a PlantSim becomes an elder and their remaining lifespan is randomly determined, they will initially be assigned 15 days as opposed to the 10 days assigned to regular Sims.
==The Sims 3==
Sims' lifespan can be set in the options menu of The Sims 3 that determines how long a Sim's natural life will be. As always, the Sim may die a premature, unnatural death, regardless of this setting.
The player can lengthen a Sim's lifespan in game without altering game settings by having them eat a Life Fruit (restores one day) or Ambrosia (resets days to age up), drink a Fountain of Youth Elixir (sets life stage to first day of young adult), become a Vegetarian or a creature like a mummy or a vampire, who live a number of days longer than a normal Sim.
Lifespan	Baby 	Toddler	Child 	Teen 	Young adult	Adult 	Elder 	Total Lifespan
Short 	1 day 	2 days 	2 days 	4 days 	6 days 	6 days 	4 days+ 	25 days+
Medium 	2 days 	4 days 	4 days 	8 days 	12 days 	12 days 	8 days+ 	50 days+
Normal 	3 days 	7 days 	7 days 	14 days 	21 days 	21 days 	17 days+ 	90 days+
Long 	6 days 	15 days	15 days	30 days 	45 days 	45 days 	34 days+ 	190 days+
Epic 	30 days	75 days	75 days	150 days	225 days 	225 days	180 days+	960 days+
Aging can also be turned off in the options menu to stop every Sim in town from aging. Drinking Age Freeze potion will disable aging of an individual Sim, regardless the aging option.
With Generations or patch 22, the length of each life stage can be adjusted individually. The length ranges from the Short lifespan to Epic:
*Babies range from 1–65 days
*Toddlers range from 2–150 days
*Children range from 2–150 days
*Teen sims range from 3–300 days
*Young Adults range from 5–450 days
*Adults range from 5–450 days
*Elders range from 4–265 days
Pets (cats, dogs, horses) also have their own lifespan, and like Sims, each of their life stage can be adjusted individually. Their lifespan option, however, is connected with Sims. If Sims have their lifespan set on Epic, the pets will also be in Epic lifespan.
===Lifespan Multiplier===
Several life states have extended lifespans. These life states have a lifespan multiplier that multiplies the default length of their young adult and adult stages.
*Mummy: 5x multiplier
*Vampire: 5x multiplier
*Unicorn: 3x multiplier (of horses)
*Genie: 2x multiplier
*Werewolf: 1.5x multiplier
*Fairy: 5x multiplier
This means that when a Sim turns into a vampire, their age length in Normal lifespan as a young adult (previously 21) becomes 21 x 5 = 105 days. Additionally, Sims who wish for long life from a genie will get a 2x multiplier on their age.
==The Sims 4==
In The Sims 4, the length of each life stage cannot be adjusted individually. However, there are three lifespans available: Short (which lasts about 48 days), Medium (which lasts around 94 days), and Long (which lasts around 364 days).
* Babies range from 1–7 days
* Toddlers range from 4–32 days
* Children range from 7–56 days
* Teen sims range from 7–56 days
* Young Adults range from 12–94 days
* Adults range from 12–94 days
* Elders range from 5–40 days
With the release of patch 142, some lifespans were adjusted again to accommodate the addition of infants. The normal lifespan for newborns was reduced from 2 days to 1. The normal lifespan for children was expanded from 13 to 14 days, young adults from 24 to 28 days, and adults from 33 to 42 days. The newly introduced infants have a normal lifespan of 5 days.
Lifespan	Newborn	Infant	Toddler	Child	Teen	Young adult	Adult	Elder	Total Lifespan
Short 	0.5 	2.5 	3.5 	7 	10.5	14 	21 	7 	66+
Normal 	1 	5 	7 	14 	21 	28 	42 	14 	132+
Long 	4 	20 	28 	56 	84 	112 	168 	56 	528+
Elders with the Active or Long-Lived traits will live longer than other Sims. Passing the "No Regrets" milestone on the Soul's Journey will extend the lifespan of a Sim. Sims can also reset to the beginning of their current life stage by drinking a Potion of Youth (aspiration reward), eating ambrosia, the essence of a Sim eaten by a Cowplant, the Age-Away Serum, or requesting Life Extension from a befriended Mother Plant. If a Sim uses the "Inhale Life Essence" interaction on scented orchid, they will either have days added their lifespan, or be reset to the beginning of their current lifestage.
Some life states experience different lifespans to regular Sims:
* Ghosts do not age and will always remain the age they were when they died.
* Vampires will stop aging once they become young adults. 
* Mermaid elders have a x3.5 multiplier to their lifespan, allowing them to live longer than most other Sims.
* Servos are always young adults and do not age.
* Werewolves will stop aging if they have Immortal Wolf ability.
==Trivia==
* If the average real-world life span of 80 years is used in an equation, then it can be calculated that one day in The Sims 3 is equivalent to about 324 real-life days.
**Using the equation above, the game considers Toddlers from 3 until 9 years old, Children until 14 years old, Teens until 27 years old, Young Adults until 46 years old, and Adults until 65 years old.
** One hour is 13.5 days and one minute is 5.4 hours.
**However, if Seasons was installed, a day in The Sims 3 has a varying equivalent of almost two days to a month in the real world depending on the user's settings.
*** On an average setting, a year in the real world would be equivalent to 28 Sim days. This would make the "normal" lifetime of a Sim (90 Sim days) really short, stopping at around 3.21 years old, and the shortest possible lifespan (22 Sim days) being less than a year, equivalent to around 286.7805 real-life days.
*** Making a Sim live at a maximum allowable lifespan (around 1928 Sim days on Epic setting), and shortening the year from Seasons (from an average of 28 Sim days to the minimum of 12 Sim days per year) would make a Sim live at a maximum lifespan of an astonishing 160 years, assuming this is not modified by any means such as consuming Ambrosia or turning into an another life state. On the other hand, the shortest possible lifespan, even with the 12-day minimum, would make a Sim live just under two years.
*In the Sims 4, if we use the equation to calculate real to Sim days, and the normal lifespan globally is about 73 years, without the Seasons expansion, we can see that anywhere between 1 and a half to 2 Sim days is equivalent to a year.
**If we use this equation we can see that Newborns are up to less than a year old, Infants are from about 0.5-2 years old, Toddlers are from around 2-5 years old, Children are from 5-13, Teenagers are about 13-22 years old, Young Adults are from 23 - 39 years old, Adults are around 39-63 and Elders are around 65-75, depending on if the Sim has Long Lived.
