I know this violates all the general wisdom that most successful YouTube videos run shorter than 2 minutes, but due to the hypnotic and soothing quality of this clip, I felt obliged to post it as a public service to high blood pressure sufferers everywhere.

I give you: Shicatsu. Some people might consider this cat porn. Diesel says, "Bring it."
PS: even more soothing with audio on.
