It seems I can never quite get enough scrubbing power to exfoliate the upper middle portion of my back. I have purchased a number of "back scrubbing devices" but I can never seem to make them work well enough. Since I live alone and have no love life, am I doomed to forever be in need of exfoliation? I was thinking maybe installing something like a cat scratching post on the shower wall that would allow me to rub my back up against it like a bear scatches his back on a tree. Maybe I will make millions of $$. Don't tell me to go to a spa, I'm not into that kind of thing. Anyone else have a solution?
