The average age for female MLC appears to be around 35 years old. Women tend to hit it alot sooner for whatever reason.
Those who married young or had children at an early age seem to start earlier as well. Plenty of woman MLCers in the 30-35 year old range...
Even when the MLC label is missing there are plenty of stories all over the Internet of 35 year old women suddenly deciding they don't want to be a mother or wife anymore and suddenly acting like teenagers.
It happens alot more often than people think! I think the reason you see so few male MLC LBS on this board is that most men just immediately divorce their now "insane" wife and move on rather than stand for their marriage.
I must admit I sometimes wonder if they aren't the smart ones, but at least I will be able to look back someday and honestly say that I tried "really really frigging hard" to save my marriage.
