The real question is, why bring age into it at all? And that becomes a question of context.
For example, if I say that I saw an old man playing Frisbee in the park with his dog, that evokes a certain mental picture, while saying that I saw a boy playing Frisbee in the park evokes a different mental picture.
OTOH, if I said in a thread that FortyTwo is a young man, and that I'm giving him leeway because of that, that statement would be both (a) true, and (b) condescending. The same would be the case if I referred to Capstan as "old man."
That's because, in the context of a discussion board like this one, age isn't relevant unless one wishes to convey that someone needs to be excused as not quite fully competent because of lack of experienced/deteriorating facilities, or one just wants to be condescending for the heck of it.
Now, I for one don't mind being called old. I am old, after all. And if someone wants to do it to be condescending, that's fine with me also, since that reflects on the speaker, not on me.
