Fanon:Declining years

In The Sims 4 (non-canon), Declining years is the life state between adult and elder. It lasts for 17 days in-game, but may be longer due to random chance.

Appearance
Sims in this life state have wrinkles, but not to the degree of the elder. Their hair will also be faded, but not fully gray. This can be fixed in Create a Sim. They may also be slightly fatter than adult sims.

Customization
Sims in the declining years have all the customization options of adult sims. They unlock a few new outfits, most of which have an elderly look to them.

Interactions and action options
Sims in the declining years take very marginally longer to do things. They can Reminisce and Tell Wild Story Of Good Old Days to other Sims. They also have a very small chance of becoming pregnant. Death by overexertion is a possibility as it is with elders, but it takes much longer. Other than this, they are capable of doing anything an adult can.

Trivia

 * The declining years was originally going to be called "middle aged".
