I very much agree with everything you have said delia, however one of your assumptions was wrong. When blue did this, she was working and had a child. It is simply a case of adapting to suit the requirements.
I think the thing I would like to re-emphasise again from delia's post is the fact that this is NOT easy, it is not something to be taken lightly, and a lot of people would not be able to cope with sustained degradation of this form.
