Grammar usage guide and real-world examplesUSAGE SUMMARY
The phrase "lifetime since" is not correct and does not convey a clear meaning in written English.

Common error
Avoid using "lifetime" when you intend to describe a general duration or time span. "Lifetime" specifically refers to the duration of a living being's existence. For general time spans, use phrases like "time since" or "period since".
