well excellent work

Thanks to you both. First, Aaron, I understand what you mean. Yet, Doctor Tushy did represent medical role-play at the time I wrote this article and I am certain it still does. Also to Steve: desire and need are very different things to me. Perhaps if you explained a bit more I would be able to give a more informed response. Cheers to you both, MT

To explain desire is to explain need, and that might not be possible
