You must purchase one size bigger in a thong than you would in your underwear size.  Sometimes having one on is more appealing than the old granny undies, and not seeing the lines.  Get the elastic kind, more fit staying.

Spinach, put some in your salad or cook some in speghetti, pts, tomatoes, raisins and prunes.   Keep a stash of raisins in your lunch box as a snack instead of the pt chips out of the snack machine.  

I heard the same thing also, when I was taking a microbioogy class, I was told they can go in the anus of a child if they are in a sand box, most times that is where you will find things like this.
