@Yehuda you made me work D minutes to resize the pic, next time just look it up your self 
Thank you. You could have just given me the Siman/Seif.

Anyway, I just went through it. It talks about not showering at all (similar to the Artscroll posted earlier), but doesn't say anything about taking less frequently than you normally do. I also want to clarify that this isn't something my Rav hasn't told me, I meant this is something I had never heard in HS or Yeshiva. I asked a friend who said he had heard of it, but said similar to other guys here that he didn't think it applied anymore saying that back then it really was a big deal for people to take showers/go to the bathhouse, but now we take showers every day, so a shower is not a big deal for us.
