If you really need to have that extra edge when you play, there's a bizarre new "Focus Trainer" from SportsLink that's supposed to improve concentration and focus before atheletic activity and really get you into "The Zone". It sounds more like a trip to the Laserium if you ask us:
First, find a nice quiet place where you won't be bothered. Put the glasses and headphones on and pick a session. You can choose from 15 of them, ranging from "relaxed calmness" to "anxiety release." Press Start and wait. After a 10-second countdown, you hear a weird noise like a soothing low feedback. It gets louder and then softer, stunted a bit and then drawn out. Then the lights kick in. There are six small, flashing lights that blink furiously on the top rim of the glasses. Shut your eyes, take some deep breaths, and the effect is really strange.
