There are some ways to delay aging. First of all, we should try our best to fulfill the citizens' whimsy to get satisfaction, and then buy "youth/potion" in the reward shop of the ambition menu, drink it on the birthday, and all the days of the current age will be cleared.

In this way, although you can't go back to a certain age, you can stay at a certain age forever. Citizens can always pursue their ambitions, careers and other goals without worrying about dying of old age.

If we ignore the aging of a citizen, when his life comes to an end, death will come and take away his soul and realize the "cycle of life". At this point, the life of citizens is over. You have to continue to play other families' games, and the skills, careers and ambitions of former citizens have disappeared.

Demand:

Sims have needs, namely bladder, hunger, energy, entertainment, social interaction and hygiene. These six basic requirements are reflected in the demand menu in the form of progress slots, and full slots indicate good status and are green; Less than 50% is in a warning state and is yellow; Less than 30% are in danger and orange; Less than 15% is in a state of emergency and is red.

Failure to meet the needs of sims in time will lead to accidents and even death of sims.
