10月1日，世界纪念国际老人日，凸显了长寿带来的机遇与挑战。
On Oct. 1, the world marks the International Day of Older Persons, highlighting both the opportunities and challenges of longer lives.
没有哪个国家比日本更直接地面临这一挑战，日本拥有全球老龄化速度最快的人口。其人口中已有超过一半年龄在50岁以上，劳动力也在老龄化。这种人口结构变化使得重新思考经济优先事项变得至关重要。维持成年人在老龄化过程中的健康与生产力是其中的核心部分。
Few countries face that challenge more directly than Japan, which has the world’s fastest-aging population. More than half of its population is already over 50, and its workforce is aging, too. This demographic shift makes rethinking economic priorities essential. Maintaining the health and productivity of adults as they age is a central part of this.
因此，随着老年依赖比超过50%，预防性健康措施必须成为日本领导人的重中之重。
Preventive health measures must therefore become a key priority for Japanese leaders as the old-age dependency ratio surpasses 50%.
