How long do you guys play with the same household/save file?

I'm curious how long other people play for. It doesn't have to be the same family with a long lifespan but I'm talking the same family tree, not switching between households.

I realized I've been playing my current sims 3 legacy for 6 months now which I feel like is pretty long. The longest I've ever played with a household was in the sims 4, the same family for a whole year. I had the lifespans set to super long so I didn't even have my original sims die yet 😅

Edit: Wow I had no idea so many simmers play their saves for so long! Here I was thinking 6 months is a long time and some of you have been playing the same one for YEARS. That's dedication
