大家知道的一個常識就是獨生子女相對難以相處一點，而最新研究把獨生子女的壞處量化了：是在婚姻家庭方麵，獨生子女更加習慣獨處，更加傾向不結婚，而且結了婚也更加傾向離婚。而多一個兄弟姐妹，則可以降低11%的離婚率。原因很簡單：兄弟姐妹一起成長過程，就是學會和他人磨合包容的過程，是一個今後成年婚姻生活的實習機會：

Meanwhile, siblings, maybe you should consider marrying other siblings (not your own), unless you feel extra confident in your people skills. And everyone, if you care about the sanctity of marriage, raise lots of kids.
