Cow's stomach

Up to early today, I had the firm belief that a cow has 9 stomachs only to realize a bit earlier that cows actually have 4 stomachs (or, more exact, 4 chambers in the stomach)... not 9... What happened to the other five? 8-O

I absolutely have no idea where I got the number "9" from...

No problem... haven't I told you so many million and a time that I am a defectory fool. 8-O lol

And, ain't it nice to learn something new everyday if not unlearning the wrong?!
