So close friends and i usually chip in to buy a gift for each others' birthdays. friend of mine supposedly wants this: http://www.brookstone.com/store/pro...id=170106&search_type=subcategory&prodtemp=t2 She has a lot of back problems, but that looks like a pretty horrible contraption, and would seem to do her more harm than good. Thoughts? and yes i'm aware that stretching parts of the back is bad, but not all. i'm sure the words stretch, spine, and back are red flags in the item description, but perchance do any of you think that thing could be helpful?
