In the US, perhaps. Maybe the ladies are just courser here in Europe but get a few of them together and they're usually coming out with language that'd make me blush.
In the upper middle classes and above, perhaps. In the working class, my personal experience is the old are just as foul mouthed as the young (although they tend to use it in the correct company, rather than everyplace). This might sound classist, but I'm working class and it's what I've experienced in any case.
