A nbap? I've never heard of one of these things....
How do I acquire one, and is having one illegal?
Yeah, nbap is a series of exercises that involves a soft pillow and a large open area enough for you to lie comfortably on. It is totally legal in the United States (though in some states, it is highly frowned upon). And, on top of that, it is, for the most part, free (there are occasionally detrimental and costly side effects, but those rarely occur under normal circumstances). I found the guidebook with some extensive Googling. I printed it out when I found it... so I didn't keep the link. Sorry.
