In other words, a moderate climate is more suitable for a longer human life. In Figure 1, all of the cities with an 85+/65+ ratio \u003e 0.07 (top quartile) were located in areas that were not very cold during winter. In fact, all these cities had an average temperature \u003e10 °C except Dandong city (7.7 °C), and most were \u003e15 °C (the average was 18 °C), had humid air (all with precipitation \u003e 550 mm; average precipitation 1345 mm; humidity \u003e 24), and low altitude (\u003c1000 m except Leshan city (1131.68 m)). The average altitude of cities with superior longevity was 201 m. However, not all the cities with moderate climates ranked within the top quartile for the longevity index. One hundred fifty-five cities had a standard deviation of monthly mean temperature \u003c 10, humidity \u003e 30, and altitude \u003c 1000 m; however, only 72 of them had an 85+/65+ ratio \u003e 0.07. In addition, the cities with highest longevity ratios do not have the lowest altitudes, lowest monthly mean temperature standard deviations, or highest humidity. Therefore, there is no significant difference in longevity between different sub-climatic types within moderate climate.","tracks":[]}
