A study from the London School of Economics and Vitality offers a quietly radical proposition: that sleeping at least seven hours within a consistent one-hour window, five nights a week, may extend a human life by four years. What the research illuminates is less a discovery than a confirmation — that the body has long known what it needs, and that modern life has made it difficult to listen. The question the findings raise is not scientific but philosophical: what does it mean to treat rest as an act of self-preservation rather than a concession to weakness?
