 Answer the question below. Please respond with the option letter (A, B, or C) first. (HINT: Each PubMedQA instance is composed of (1) a question which is either an existing research article title or derived from one, (2) a context which is the corresponding abstract without its conclusion, (3) a long answer, which is the conclusion of the abstract and, presumably, answers the research question, and (4) a yes/no/maybe answer which summarizes the conclusion.) 

Question:
Optimism and survival: does an optimistic outlook predict better survival at advanced ages?

[2025-09-25T12:41:58.461521] [PI reasoning] **Evaluating optimism and survival**

I'm examining the question, "Does an optimistic outlook predict better survival at advanced ages?" It seems like the title of a research article. I need to pick a conclusion: yes, no, or maybe. I recall a paper regarding the Leiden 85-plus Study, which explored optimism's impact on survival for those aged 85 and older. From my memory, it suggests that optimism is associated with lower mortality. However, I'll double-check for accuracy and specifics on the findings.
