I have not heard of that term before I read this listing. I have a mom that is almost 78. Right now she is still living on her own but I do check in on her or call her. I take Mom grocery shopping and to church. If she needs anything she knows she can call me. I am lucky she is still on her own but I am close if she needs anything. She is on oxygen 100 percent of the time. She already told me that she does not want to put that on any of her kids, she wants to go into a nursing home if that time ever comes. But, some parents wont or can not do that. But for more information check out http://www.californialistens.com/2008/07/18/the-sandwich-generation.html
