This work concerns the older generations as well as the new ones. In today's world, we often find that the older generations are often forgotten. Young people are not interested in them. Unfortunately, in 2014, the silent generation (born between 1925 and 1942) is gradually disappearing. It's not just the individual who's disappearing, but everything they know, their culture, their way of life and their way of being. Quite simply, their memory vanishes without a trace. Many prejudices have developed between the generations, particularly between the younger and the older generations. Each generation has a fairly poor perception of the other. There is a total lack of interest between them, whereas the older generation possesses an enormous amount of knowledge that could be useful to everyone. This memory that the silent generation possesses can be preserved in different ways. It can be an oral memory, when the person recounts what they have known, their knowledge. There is also thephotographic memory and the digital memory, which can store and preserve a huge amount of information.
