这本来就是好事，从来不是坏事

生孩子当然是好事，哪里是坏事。A woman's peak reproductive years are between the late teens and late 20s. By age 30, fertility (the ability to get pregnant) starts to decline. This decline happens faster once you reach your mid-30s. By 45, fertility has declined so much that getting pregnant naturally is unlikely. - American Congress of Obstetricians and Gynecologists

从医学角度来说，高中生就是生育的好年龄。从长远角度看，一个女孩读H，然后追求事业，高工资，但只有一个孩子（甚至没有孩子），相对另外一个女孩，普通大学，做全职妈妈，生育和培养4-5个孩子，最后哪个自己幸福，哪个给社会贡献大？
