I know this is very Mitt Romney saying his favorite meat is hot dog, but I like to throw around a ball. I turn my brain off and lay on the couch and toss it up and down. I bounce it against a wall. The best version is sitting around with a friend and having a catch while chatting. Any ball: Tennis ball, Pinky ball, stress ball, whatever. At the time of writing, I have a purple grocery store ball and two foam tennis balls in my arsenal. Foam tennis balls are good because when you inevitably hit the TV, it won’t fall over.
