No Pain, No Gain?

I saw this at the Paper Dreams store where Cynthia and I went this afternoon. It's a mat covered with hard, spiky plastic discs. You're supposed to lie on it -- after you've purchased it, and not in the store, thank you. For consenting adults only, I presume.

Cynthia shared her "Dream Wheel"prize with me. I'm not supposed to tell you what she won, but there were four kinds, and they were all delicious. I won 30% off my purchase -- not too shabby!
