Common error
Avoid using "were valid for a lifetime" when the validity is conditional or subject to change. If there are specific conditions that could void the validity, it's more accurate to specify those conditions rather than implying indefinite validity.

Ludwig's WRAP-UP
The phrase "were valid for a lifetime" is grammatically sound and intends to express the enduring validity of something for the entirety of a lifetime. However, Ludwig indicates that the phrase is rarely used in real-world contexts, suggesting limited practical application. When employing this phrase, it's essential to clearly define what 'lifetime' refers to and avoid overgeneralizing its scope. Similar phrases like "lasted a lifetime" or "remained effective indefinitely" may provide alternative ways to express the same idea. Therefore, while grammatically correct, careful consideration should be given to the specific context to ensure accurate and effective communication.
