Cupping hasn't been scientifically proven to actually have any health merits. I rank it right up there with tying a string to your finger to get rid of a sty, or a cyst, and like holding your hand up in the air to stop a nosebleed.

Of course, when it comes to Justin Bieber getting the treatment done, all I can say is that the cups weren't big enough, and the person applying them didn't use enough vacuum. The little twerp is still around, and just as obnoxious as ever.
