at least most ladies I know give birth to their first baby after 40! are you a med student or a physician? if not, shut up and stop your ridiculous as......

这个是有统计数据的啊，这么义愤简直莫名其妙。而且打定主意丁克的人是不是应该更淡定点啊，反正又不要生。

A woman’s best reproductive years are in her 20s. Fertility gradually declines in the 30s, particularly after age 35. Each month that she tries, a healthy, fertile 30-year-old woman has a 20% chance of getting pregnant. That means that for every 100 fertile 30-year-old women trying to get pregnant in 1 cycle, 20 will be successful and the other 80 will have to try again. By age 40, a woman’s chance is less than 5% per cycle, so fewer than 5 out of every 100 women are expected to be successful each month. quote from Age and Fertility by the American Society for Reproductive Medicine

unless the couple have rich parents or they are really lucky in their career, giving birth to 1st baby after 40 is sooooooo normal nowadays.

这是个 trade off的问题，非要说有钱人才能生小孩真不是一般的偏激，那样的话人类早灭绝了。
