However, wealth and health were found to have little effect on happiness. The researchers said the find could help explain why some of the worlds poorest nations are also the happiest.
然而，研究发现财富和健康对幸福并无多大影响。研究人员说这项发现有助于解释为什么世界上最贫穷的一些国家也是最幸福的。

研究的作者之一、瓦尔纳管理大学的迈克尔明科夫说：我们发现美洲、非洲的赤道和热带地区幸福基因较多，地中海地区的幸福基因比北欧地区要少。
