In recent years we have heard a lot about the term "ageism", a concept that, as the word itself indicates, refers to a type of discrimination based on age. Currently considered one of the most widespread forms of discrimination, along with racism and sexism, it is still largely unknown to society in general. Given the topicality and growing interest that seems to generate this issue, from the Lugaritz housing construction team we have decided to organize a talk in which we will have Elena del Barrio, co-director of Matia Institute and expert on the subject.
