It's a physical fact that older people's bodies aren't as able to fight off diseases, and they are likelier to have mortality rates.

If no one's allowed to actually explain the physical facts of how the physical universe works, because it's "insensitive" to mention that older people are more likely to die when they're sick, how is our society supposed to come to correct [1] answers when it comes to medical science and health policy?

[1] By "correct," I mean minimizing the incidence and severity of illness within relevant resource constraints.
