The longevity revolution: how science and society are redefining old age in the 21st century

In recent developments concerning twentieth- and twenty-first-century societal shifts, two distinct stories have emerged regarding notable individuals and demographic transformations. In Mexico City, prominent radio and television journalist Óscar Mario Beteta passed away on Wednesday, September 9, at the age of 70, concluding a career marked by extensive media longevity alongside his final personal relationship with Araceli Pedraza.

Simultaneously, broader societal changes regarding aging are being re-examined through scientific and cultural lenses. The demographic transformation of the twenty-first century is the subject of Nora Bär's essay, *La nueva gerontolescencia*, which explores how science and society are redefining old age, highlighted by the notion that aging is connected to one's vitality and outlook on life.
