Why do a lot if not all woman at a certain age (40) have the ability to flip/flop?

I have noticed over the years a strange phenomena in women around the age of 40. They have the ability to turn from careing understanding adults to completly uncareing imature distructive children or worse and without any consicence about who or what the destroy or ruin including relationships, jobs, picnics, songs, dinners, days, breakfasts', families, etc...I could go on and on. Most men at that age seem to try to avoid such foolishness whats up with that?|||It happens far more to men than to women.|||They're women, what else can be said?|||COOL|||yes, men start in on that at age 45. It has something to do with the onset of menopause, instability, their world changing, they think it's their last chance at fun (even abusive fun and entertainment). It also has to do with the stress of everyday living knowing that they should have reached the height of their career at that age and if they haven't then there's a lot of competition, drinking, etc. They also let their hair down because they have had their kids and have no reason to really attract the opposite sex. But you know, more and more women are in public jobs and that's very competitive and stressful as well.|||really well i flip flop for the better then. i've started beleivingin God more and shutting my mouth. back in the day i could drink someone under the table and party all night long. i just thought having a child and age was the one that squared me up. i guess i just starting flip flopping 15 years ago. now i am a much nicer ida.|||Suddenly, she realized that she had no reason to darn another sock.
