@Linkat,
I totally wanted to try the fishy thing when I first read about it (coupla years ago). I grew up in Minnesota, Land of 10,000 Lakes All Teeming With Tiny Fish That Like To Nibble On Toes. I don't know how much dead skin they got but I always thought that was entertaining.
This latest stuff about the bacteria yadda yadda is offputting though.
When I was searching for something about the Ohio regulations (I was told that about no more foot-shaving, dunno if it's true), I found recommendations that you not shave your legs for 24 hrs before getting a pedicure, too, because of scary cases of infection. Eek.
