but the demographers tell us that probably the natural human lifespan is something like 85 years ± 5
人口统计学家会说人的自然平均寿命是85±5岁

如果我们没有胎死腹中

所以，应该照着做，该干什么，不该干什么
not because some particular industry want you to do but because it'll make you live longer and healthier
这不是为了讨好某个行业而是为人的健康长寿着想
Now this gets expressed actually in some interesting factual data
