工作原理

使用联合国《世界人口展望》中150多个国家的平均预期寿命数据。
根据男性、女性或全国平均值调整估算结果。
将各国按医疗水平分级，便于您了解自身所在国家的相对位置。
以周为单位的网格形式呈现您的人生，每行代表一年。

这是一个统计学上的平均值，并非针对个人的预测。个人健康状况、生活方式、家族病史和运气等因素，远比一个国家的平均数据更重要。

常见问题

预期寿命是如何计算的？

预期寿命基于联合国《世界人口展望2024》的统计平均值。它代表在特定国家出生的人经性别调整后可预期存活的平均年数。

我真的能活得比预期寿命更长吗？

当然可以。预期寿命只是一个统计平均值。许多人活得远超平均值。饮食、运动、医疗资源、遗传和生活方式选择等因素都会影响个人寿命。

为什么女性比男性寿命更长？

在全球范围内，女性平均比男性多活4-7年。这归因于生物学因素（激素保护、两条X染色体）、行为差异（较少冒险、较少吸烟/饮酒）以及社会因素。
