    The Great Doubling: 500 Years of Global Longevity Historyのベスト引用

    “

    In just two centuries, we’ve more than doubled the time we get on this planet. We often think of history as a slow, steady crawl, but when it comes to longevity, we’ve essentially lived through a vertical liftoff.

    よくある質問

    For most of the last five centuries, global life expectancy remained remarkably low, with no region in the world exceeding a forty-year average as late as 1800. In places like London, the average newborn was only expected to live about thirty-two years. However, the last two centuries have seen a vertical liftoff in longevity, with the global average reaching seventy-one years by 2021, effectively doubling the time humans get on this planet.

    The dramatic increase in human lifespan is not the result of a single medical breakthrough but rather a mosaic of societal and scientific changes. Key drivers include improvements in nutrition, the implementation of clean water systems, and the development of vaccines. Additionally, advancements in sanitation and changes in how we build our homes have played critical roles in the evolution of public health and the extension of life.

    In the year 1800, reaching old age was a luxury that very few people could count on. Because the average life expectancy was only around thirty-two years, the demographic makeup of cities like London was strikingly young. This historical ceiling on longevity meant that for the majority of human history, the typical life experience was significantly shorter than the eighty or sixty years we often expect in modern times.
