Life Extension?

[Caitlin]

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?

My vegetarian male with the marathon runner athletic achievement died younger than his meat-eating, sedentary wife. He lived to 93; she lived to 95.

My elders have ranged 90 - 125 at the time of death.  None were vegetarians or athletes.  I honestly can't see any reason why some outlived others.

According to the code, Elders' minimum age is 2.428 multiplied for the constant k[lifespan]SimDaysPerAgingYear, which is 2 for Short, 4 for Medium, 7 for Normal, 15 for Long, 75 for Epic.

This means the minimum age in days for Elders should be:

• 4.856 for Short lifespan (25 days total)
• 9.712 for Medium lifespan (50 days total)
• 16.996 for Normal lifespan (90 days total)
• 36.42 for Long lifespan (190 days total)
• 182.1 for Epic lifespan (970 days total)

After this minimum, each day there's a probability the elder will die, as follows:

• 30% for Short lifespan
• 20% for Medium lifespan
• 14% for Normal lifespan
• 6% for Long lifespan
• 3% for Epic lifespan

The only modifier I found is for elder marathon runners (max athletic?), which have their daily chance of dying multiplied for 0.75 - for example 10.5% instead of 14% in case of Normal lifespan.
Unless there's something else hardcoded elsewhere, this seems to be the only thing that affects lifespan.

BTW I foresee Elders' persistence in case of Epic lifespan truly terrifying.

I guess that explains why Flo Broke was around for three generations in one of my Riverview games. She only had a 6% chance to die per day. I guess she was just lucky.
