When I see adverts (tv, radio, print media, online, the lot) I expect them to reflect a cross section of the public over all kinds of adverts; young middle-aged, old, all colours, all genders, all heights and sizes - and they do not.
In France I picked up a brochure about new telephones and technology and it did just that complete with a very eyeable white haired older man showing his grandchildren how something worked.
Recently an advert outside a local very sheltered housing development the advertisement for the development featured a gurning fit older couple, all white hair. and white teeth, looking as if they were sailing an ocean yacht, which were completely unrepresentative of the kind of residents these flats were designed for.
