How long will a turbo engine last?

Could you elaborate on the durability of a turbo engine and its potential lifespan? I'm curious to know the factors that can influence its longevity, such as maintenance practices, driving habits, and the quality of the engine itself. Are there any common issues or wear patterns that tend to emerge over time? Additionally, I'm wondering if there are any specific signs or symptoms that indicate when a turbo engine might be nearing the end of its useful life. Could you provide some insight into the average lifespan of a turbo engine and how it compares to a naturally aspirated engine?
