At What Point Do You Stop Playing a Save? UPDATE

My current save has been going since February 2021. Just when the last of my sim self's children are out of the house, MCCC throws a curveball and he somehow manages to have several more children while playing other households. My plans for him to age up to elder get put on hold but that's a good thing as i get to keep him as an adult for a few more sim years as i reset his adult life stage back to the beginning when more kids come along.
