An old fool is the worst of fools.

Understand the thought
Meaning in plain English
Poor judgment can seem especially disappointing when someone has had many opportunities to learn. Age supplies the contrast with an expected growth in wisdom.
What the words are saying
The saying criticises foolishness that persists despite experience. Its force comes from an expectation that time should have supplied lessons, rather than from proof that older people necessarily know better. It can describe someone repeating a particular avoidable mistake after seeing its consequences. The broad insult should not become a judgment on age, memory or disability. A more useful reading identifies the behaviour and the missed opportunity to reflect, while recognising that anyone can continue learning at any stage.
Everyday example
Someone repeats the same preventable planning mistake despite several chances to review what went wrong.
When to use it
Use it cautiously to discuss a repeated mistake rather than a person’s age.
What it does not mean
Experience does not guarantee wisdom, and age is not evidence of foolishness.
