The way you're communicating, are obsessing over dictionary definitions without taking into consideration context,

Is she old? The dictionary says she is. She is relative to the ages of the people we're comparing her. She is according to how people use the word. If I look at an insect preserved in amber, I'm not gonna say it's young just because it didn't progress physically when it is indeed old.

You're just completely ignoring everything and saying she's not old because, well, you say so. That's all you're arguing, she isn't because you don't think she is, you have no basis, you just use the word old wrong. You try to claim she's youthful, and therefore not old, when both definitions fit her, hence what not being mutually exclusive means.

It's not an insult.

If you ask if someone has a disorder because you can't let go of your own visualization of a word in thinking that old has to be directly related to the physical ageing and deterioration of a person, it's fucking disrespectful, it's an insult.

Don't argue about semantics if you don't plan to actually care about what a word means.
