[2025-09-25T12:02:11.488581] [PI reasoning] **Evaluating kidney transplant suitability**

I need to think through the question about implanting kidneys from elderly donors in young recipients. Based on transplant guidelines, older kidneys are often given to older recipients, as they generally have poorer outcomes when matched with younger ones. Historically, studies discourage this practice, suggesting it’s not appropriate. Therefore, I'm leaning towards answering “no.” However, since we don’t have an abstract to confirm, I might need to verify this quickly.
