For Doodlebug, and that "She's entitled to an opinion, but Facebook isn't really for discussion". F'book isn't really for discussion?
Sorry, but people can (and do) post all sorts of misleading or downright wrong stuff on there, and why shouldn't it be discussed and corrected if necessary?
Re this actual example, I've reached the age myself (I'd be getting a free TV licence in a few months, but for the Tories) where some mornings the body feels like it needs a full service just to get downstairs and make tea, but I'm also well aware that both parents didn't see 52, so I'm loathe to complain too much!
