Totally agree on every point and I'm not being negative, the thing is that stating the age is something most people wouldn't even think (I like to believe we all still see ourselves as kids in our minds), so if someone puts it there themselves (as opposed to being a news article written by someone else) then they are doing it for marketing purposes.
