I don’t know about that. Granted I am still young so I may not have much life experience compared to older people, but my mom in her retirement years have been reckoning and expressed regret of her past life decisions. She is dogmatic in many things (influenced by her rural and religious conservative upbringing); always sure of herself; has bit of ego and typically don’t admit having made mistakes even though it is clear as day. But she had figured out that she had been wrong on so many things. She turned around on many views that had proven to be wrong. But my mom still being my mom, she pretends though that she has always held the opposing views that she now adopts.
