Therefore, the reason that intelligence and death are linked might be that people with higher intelligence in childhood make better decisions about health, and have healthier behaviors. As adults, they tend to have better diets, exercise more, gain less weight, have fewer hangovers, and so on.
因此，智力和死亡相关的原因可能是，儿童时期智力水平更高的人对身体健康问题做出更好的决定，而且行为也更加健康。作为成年人，他们一般饮食搭配较好，锻炼更多，体重增加较少，不大喝醉酒等等。
