Desc: Le petit caillou: Directed by Isabelle Capiaux. How do you age in your host country when you are a migrant? Are we thinking of returning to our country of origin or are we staying close to our children and our social network, built year after year? At retirement age, some decide to return to their homeland while others prefer to age where they have built their friendly, professional and family lives. Belgium, which has been confronted with this issue for some years now, must consider innovative solutions, while taking into account the specificities of this aging migrant population.
