Ageism is prejudiced behavior of society against the elderly: according to jared diamond in the video: how societies can grow old better: Our protestant work ethic, which places high value on work, so older people who are no longer working aren"t respected. Another reason is our american emphasis on the virtues of self-reliance and independence, so we instinctively look down on older people who are no longer self-reliant and independent. 1/3 is genetic, 2/3 is not genetic (who is the largest demographic in the world?)
