Sorry if I seem a little dense. But does this change all the age lengths equally or are the age lengths in modified proportions?

I assume "Standard" is what EA calls "Normal" Aging?

Jeffs0418- the ages in all age lengths are proportional to each other, or at least should be. Things might get wacky at shorter age lengths, as I haven't tested them, and the code doesn't work quite as I expected.
Severedsolo- yes.

I don't understand this at all. What do the numbers mean next to the lifetime names? Like why does it say Long-12? Can you elaborate a little more so it makes more sense? Does it mean that 72 is the base length and the numbers at the end of the lifetime names are how many days are added?

I'm so lost, durrr.

Those are numbers used in the code. Each age length has a certain base length (like, say, 2), which is multiplied by the aging year length of whatever you are playing at. Let's say the Teen stage is 2 aging years long and you play on Long, which has, say, 10 days per aging year. Therefore, the Teen stage will be 20 days. I should have made this clearer in my main post.

Eh... such a short life...
I think I'll keep my sims alive for a minimum of 960 days..

How, exactly, do you install this? Does it go in Mods --> Packages? When I put it there, it didn't do anything.

It goes in the default location. If it doesn't work, then you must have the framework installed incorrectly.

Does it work with LN?

The mod itself is updated. However, I haven't run the game with it so I can update the screenshots, so I haven't posted the new version yet.

@potatoehead
Are you deliberately trying to be confusing?
Your explaination of how this effects the length of each age group couldn't be more incoherent if you tried.

has the mod been tested with late night and does it affect the vampires?

@keekee53 -> what an intelligent person you are indeed !
Next to the Normal is written 6 and, magic ! the only lifestage that as 6 days in it are children. So, since 6 enters two times in 12, it means that the Long lifespan is twice the normal. So teenagers will have 18 days, young/adults will have 40.
And since 6 enters 10 times in 60, it means that....yes, teen will have 90 and adults 200 ! Isn't that just wonderful

Eh I prefer the really long lives. Gives me time to do everything that I want with my sims. But nice work anyway

If you know some XML tuning you could technically edit his mod to make the EA default lifespans even BIGGER. So.. the epic lifespan would be even more epicly long.

@Dougy--Hey, no need to be snippy. I found the language to be confusing, too.
Will definitely download! I hate playing EA's "normal" lifespan for teenagers because there are some tasks that are impossible to achieve...but I hate playing anything longer because the dangged sings already live too long!

I have decided that the baby stage in game is really long in vanilla. I'm not sure what stage I'm playing, probably epic since my young adults still have 120 days till they become adults, but their babies don't turn toddlers for another 13 days and they're already 17 days old. In real life you're a baby for like, a year, maybe two, (I'd prefer one since babies can't do ANYTHING) you're a toddler for four to five years (six-year-olds aren't getting homework yet, but they play on playgrounds and some read, so this line is fuzzy. I'd rather be playing a kid than a toddler though), a kid for six years, and a teen for six years. That is about one fourth of your life. Not half of your life.

Then I'd say you're a young adult for about 12 years (till you're 30?) and then you're not an elder till your 60 (AARP accepts 55-year-olds but I think 55 is still considerably young) and even then people still don't have white hair so I'd say you could say people become elders at 65. So that's 30-35 years of being an adult. And then an elder would live 5-35 more years, depending on how healthy they've been.
I would much rather play on a ratio based by those numbers.
Sorry this is just my opinion, it's nothing against your download and frankly it's slightly off-topic.

How exactly do I use this? (sorry for being a bother, it did not say anywhere how to use this)

why cant u just change ur teen's life span urself? its in options

But wasn't originally. There was an unmet need when Mr. Potatoehead did this work.
