Well, I'm not necessarily part of the "you two" to which your question was directed Oryan, but thought i'd put in my two cents anyway =P

Some people do bring an ed upon themselves of their own will. (pro ana websites etc are examples of this). Some think that they can just use it as a "get slim quick" diet type thing and then stop whenever they please...but then fall into the trap and under the relentless control of the ed.

It's kind of an example of when the creation outgrows and overpowers the creator I think.
