[NEEDS INPUT] No longer get bonus days for maxing fitness

This just came up for me in my legacy game. I play with no mods or cc, never used. It's my first experience with the long-lived trait, so I wasn't sure how it was supposed to work anyway. Glad to see it explained. I can only go by "days lived" and unfortunately, didn't count the number of days before my first sim hit the "demise day". I have two sims that completed the athlete aspiration. Here's the little detail that I can provide right now:

The female sim with the long-lived trait completed the aspiration as a young adult. She used a potion of youth at the end of her young adult phase (and had already completed the aspiration). She just aged up to elder, and shows 114 days lived. I will track how many days she gets before her death day.

The male sim with the long-lived trait completed the aspiration as an adult, and used no potion of youth or other life-extending method, but I had no idea how many days he had when he aged up. When he reached his death date, I was very surprised as I expected a longer lifespan in the elder stage. I didn't count for certain at the time, but it seemed to be about the same amount of time as the others who have passed from old age (around 10 days). I've recovered the file to shortly before he aged up, so will test age to death in a couple of scenarios. So far, when he aged to elder, he showed 87 days lived. I've made both save files where he aged up with the aspiration completed, and without the aspiration completed (to be completed as an elder).

Now that I know the number of days I'm supposed to have with and without the trait, I'll report back on the results of the testing. Thanks for confirming my suspicions that the trait was not working correctly.

I don't know if my Sims got their bonus days of not, but I have noticed that my elder Sim who has completed the Bodybuilder Aspiration is getting dangerously tired from his morning jog. Previous Sims who've completed this Aspiration have not had this problem.

It's taken some time for me to get back to this, but I wanted to let you know that I tested this during regular gameplay with a set of twins in my legacy challenge. One maxed fitness (no aspiration or long-lived trait), the other was at level 9 when aged to elder. Both died of old age at the exact same time, within 24 sim-hours of getting the message "long life coming to an end". 

Both of the sims from earlier that had the long-lived trait did live the extra 17/18 days past the "long life coming to an end" message. I did get the "dangerously tired" moodlet for the one that remained in the athlete career, when he went for a jog. I thought the long-lived trait was supposed to guard against that.

So, I can confirm that in my game the maxed fitness does not add any bonus days to the sim's life. The long-lived trait does add the appropriate number of bonus days, but does not appear to guard against physical activity / death by exhaustion. 

I can't comment on the number of days since I'm no longer playing the household with the sim who completed the aspiration, but I can confirm that he constantly got the dangerously tired moodlet when he became an elder and I didn't remember that happening in the past (though granted I don't play with elders that often).  It got so that I had to take all the fitness equipment out of the house because my active elder kept using it and would always come off with that moodlet (I was playing the Drifter Challenge and he was one of the sims I wasn't supposed to control, though this was at least six months ago, probably a bit more). 

Thanks and regards,
