Sim lifespan seems pretty variable- some Elders live to 90, others to over 120- but are there definitive benefits from traits and perks? Does the Vegetarian trait or Marathon Runner athletic accomplishment add a set number of days to a Sims life? For even more questioney goodness, do any perks gained while a Sim is an elder make any difference on their lifespan? I'm currently testing the Vegetarian vs non-Vegetarian lifespan, but has anyone else discovered, either in code or in gameplay, facts relating to lifespan?
