First off this is a great show and it's also very informative
And with that being said the smoking by EVERYONE in just about every episode has become annoying and that's putting it mildly.. I am a former smoker and whenever I see someone smoking it literally leaves a bad taste in my mouth.. I understand their using cigarettes to show the times and how acceptable the horrible habit was "back then" but it provides nothing to any of the stories.. It's truly unneeded and it's gross..!
