In an age where youth has become an absolute value, this book explores the symbolic, aesthetic, and existential implications of the cult of vitality. Old age is no longer seen as a phase of life, but as a flaw that undermines visibility, relevance, and belonging. The young body is turned into a norm, while experience, silence, and maturity are pushed to the margins. This reflection goes beyond denouncing the exclusion of aging bodies — it questions the very notion of youth when emptied of depth and commodified. Without yielding to nostalgia, the text proposes an ethical reconciliation with lived time, with the value of presence that no longer needs to perform, and with the freedom to exist without spectacle. Between the glorification of youth and the symbolic disappearance of old age, what can still be called life?
