I am afraid that too many younger people had to wake up in a period of disillusions, indifference, sick-minded fanatism, mass production, environmental disasters, poverty, wars, corruption, wasteful consumerism, violence, abuse and crimes and shattered dreams.
Many are looking towards a precarious future, controversed values, performance stress, lost ideals and having to assume the failures of the former generations. They are also confronted with unnatural standards regarding beauty, image, health, skills, moralities, attitudes, prejudices and social status.
They try to escape to artificial fantasy worlds, modern music, movies, TV sports, on-line gaming, blogging, sharing selfies, family and friends' events, collecting on-line friends, dating, etc., and history, geography, classic literature and arts, biology, etc., seem to be a loss of time.
And middle-aged people are often so busy that they have no time left for their literature or historical groups.
As to older people, well, they are often considered old fashioned - lol.
