Simple data design flaw, or the absence of such. "Ms", "Miss", etc is only a title and that's about it. Want a flag child/adult, well, add it then. Or better yet, use age to determine average weight even more accurately. Edit: It usually means a disaster when people try to read "between the lines". One favourite example is trying to infer purpose/role of the server based on its hostname. When hostname starts with "X" it means only one thing - the first character of the hostname is "X", no more, no less.
