Longevity was undoubtedly costly...
The combination of the Black Turtle and White Serpent was the pinnacle of Vitality enhancements, and Selphira had managed by luck to bring both to ranks never before achieved.
Enormous luck... Unfortunately in a chaotic youth. She hadn't catalogued her chaotic and unorthodox numerous "small changes" to the family cultivation methods.
Her first children had lived long and full lives, dying of old age in their beds surrounded by their own grandchildren.
A family with long histories, most showing complications in health or mind only after 200 years.
It had been painful, but eventually she managed to accept it as natural.
Time heals everything...
She seemed to have too much of it. But it was something she understood and could accept.
