there is no fool like an old fool
1
used to suggest that an older person who behaves foolishly is especially deserving of criticism for not having learned from their past experiences
The origin of the proverb "there is no fool like an old fool" is rooted in English-speaking cultures, where it is believed that with age comes wisdom. The saying highlights the idea that with age comes the expectation of greater wisdom, so when an older person acts foolishly, it is seen as more surprising or disappointing. It serves as a reminder that wisdom is expected to grow with age, and people should be mindful of their actions as they grow older.
