"...many here also don't know any biology."
The problem is that many don't know how to read. We all know Mary should have felt her clock ticking. But that is in the past. Now she has a baby and the advice concerned the future.
Of course another topic is whether hearing the clock is a good reason for going out to tackle some sperm without first establishing a better home environment.
No, Mary Cheney doesn't have a baby; it's still in utero and would NOT be viable, if extracted from that place. There was NO real "advice" given; just some condescending drivel.
