preferred lifespan?

I like to have as much time with my Simmies as possible. I play on Long. That way I can age up my Sims, when I'm ready to do so. ;) I used to play on Epic in Sims3 and change the sliders around to suit me. In this iteration, I was annoyed we didn't get that, but I have found my own workaround. And yes, I do use MCCC and just learned recently why setting the number of days per age wasn't working for me, so now I have an option I didn't have before. But, I don't always keep to the 'script'. Sometimes I will age Sims up sooner than originally intended. For instance, once DU came out I wanted all four of my teens to go together and share a dorm room. Wanted to get them through university in one fell swoop. So, in order to keep their birth order, I started with the eldest and had him apply for a scholarship. The next day I aged him up. Leaving a day in between Sims, I did the same for his next younger brother. And so on and so forth until all four were aged up. Then I used the cheat for uni and sent Aaron to the uni of choice. I had him claim a bed, saved the game and went back to their home lot. I did the same until all four were at Britechester-U, in the same dorm and decided I would play each term back-to-back until they graduated. The only problem with this is that the only sister and youngest of the four, was about a day behind in her classes. But, it worked out in the end, except for a mod I was experimenting with. I have recently restarted them from a copy of the family held safely in My Library. I do like this method brought to us by Sims 4. I've even found a way to skill them up and save them with said skills. Makes for a shorter path to a restart. Sadly, I've suffered too many restarts. LOL But, I'll get over it.
