On the other hand, my understanding of the warm-blooded naked mole rat in captivity is that it doesn’t show clear signs of increasing mortality over time. We haven’t kept enough naked mole rats for long enough to see how long that lasts or whether that result is robust. But we should care at least as much about increasing rates of mortality over time—which is what it conventionally means to “age” and is captured in the concept of “healthspan”—as we care about lifespan.
Edit: I’m wrong! Naked mole rats are basically cold blooded.
