智商高的人比較健康？

英國的愛丁堡大學，用英國的 BioBank 資料分析智商(intelliegnece)和健康、疾病的關係。樣品數量為十萬一千多人(N = 112,151 individuals, with 58,914 females)，年齡於 40-73 歲之間。

* 記憶, verbal reasoning 和反應比較快的人比較不容易有高血壓、老人痴呆症或糖尿病，整體健康也比較好。

* "people with more genes linked to cardiovascular disease tended to have lower reasoning ability."

* 之前有學者認為社經地位導致於低教育的人身體也比較不健康，不過這裡發現，即使是同樣是社經地位低的，智商高的人也比智商低的保持健康的機率高。

* "even in healthy individuals, being at high polygenic risk for coronary artery disease, type 2 diabetes or high blood pressure is associated with lower cognitive function and lower educational attainment."（即使是健康的個體，高心血管激病、糖尿病或高血壓的風險是和低認知能力和低教育程度相關聯的。）
