Andy Choy's Non Sequitur

I was talking to a friend about the prevalence of peers using fertility drugs or seeking invitro fertilization. I was quite frankly shocked that healthy, successful people in their early thirties are having difficulties conceiving. Her theory was that some of these over-achievers may simply be overly anxious and impatient about having a child. In thinking about it more, I think her theory makes more sense than anything I came up with.

So are you people just impatient or is there something else going on here which is adversely affecting fertility?
