"Being of sound mind and body" to me precludes NPD and BPD in many instances.

I found this quote upstream and I found it disturbing.
When dealing with PD's, there is personal responsibility that needs to be addressed in this post. There are many famous & high functioning people with NPD & BPD.
In my own experience, I have been diagnosed with PTSD & BPD. By taking personal responsibility for my own mental health, I worked extremely hard to find psychiatrists & psychologists who were trained with DBT & EMDR therapy. At the beginning, I took medications. If the medications were not working for me, I was quick to self-report that the medications were not right for me.
Through hard work and diligence, shopping around for the best fitting psychiatrists & psychologists - and working at home on Marsha Linehan's DBT workbooks (which are available for free online by the way - or for a nominal fee at Amazon) I improved my life, my health, my happiness.
To make an erroneous, irresponsible and sweeping generalization that NPD & BPD precludes some from being of "sound mind and body" is not only wreckless, it is dangerous to engage is this type of judgement - particularly when taking personal responsibilty and hard work can make great changes.
To those who have or suspect they may have NPD or BPD, there is help. Do your own research on the internet and please do not believe judgemental, sweeping accusations.
Moo.
