>> "Want to feel old? Yes."

> No you don't.

Maybe I missed something but I don’t know what you’re quoting or paraphrasing. In the comic the guy is saying he’s glad they’re getting old together, not that he’s glad they feel old. I don’t want to speak for my brother, but it seems weird to assume he is unfamiliar with what aging entails. Personally, I’m thrilled my sister-in-law is getting to experience the pains of aging instead of late stage cancer treatment.
