I see about your age as meaning Kirk in his mid thirties and Pike at around fifty are both middle aged.
Ok, so this brings up the question; just how old was Mendez? The Actor at the time was only 38 so if you are saying Pike was around fifty how old was Mendez suppose to be. It's kind of weird to say something like "About your age" when the guy he is talking about is as old or older than he is. Is Mendez suppose to be 55 or 60 years old? I just think it is a bad line of dialog personally. Logically Pike should be at least in his mid-40's by that time and I imagine that Mendez was around 50 years old.
