Understand the thought
Meaning in plain English
The saying divides people after thirty into fools or physicians. It exaggerates an expectation that age should bring knowledge of oneself.
What the words are saying
Either and every leave no room for other possibilities, making the division deliberately stark. A qualified reading can discuss learning from experience without claiming that a birthday creates clinical expertise. Nor should a person’s health difficulties be taken as proof of foolishness. The actual knowledge and circumstances matter more than the age boundary in the phrase.
Everyday example
Someone reflects on lessons from past experience while acknowledging questions their experience has not answered.
When to use it
Use it to examine an exaggerated age-based expectation of understanding.
