去看了這篇文章，說到 "sexual activity is associated with wages" 這裡用的字眼是 associate 所以是說相關關係，不是因果關係。要注意喔!! 呵呵!!
而且有提到 "health, cognitive and non-cognitive skills and personality are important factors that affect the wage level" 這表示性生活頻率只是影響(應該說關聯)薪資中的一小部分。
literature suggests that physical and mental health, as well as personality characteristics, are important factors that affect wages. 所以影響(應該說關聯)薪資的是人格特質與心理/生理健康狀況，作為健康狀況的一環----性生活也跟薪資水平相關聯。
