[Update!] How long does it take for Elders to die?

Update!

She finally died while at work not even 24 hours after witnessing her youngest daughter (Sonya) pass away of old age at 130 days.

Luckily her grandson was able to use the Death Flower on the Grim Reaper. I didn't realize that it doesn't reset their age bar, it keeps it in the white glowing phase.

I had to use a youth potion to reset it... she's 190! Still kicking (once again!) and back to her goal of maxing all skills. Until next time Grim Reaper!
