Now, I'm not sure what is going on in this picture but it looks to me like this fellow, who may be some sort of racecar driver, motorcyclist, welder, or astronaut as the sweet but sort of unnecessary old school helmet would lead us to believe, is suffering from a headache located behind the eyes and spreading backwards, though the pain probably stems from the tension in the left side of his neck and shoulder specifically caused by problems in the 3rd and 7th vertebrae. That's what happens when you spend your days trying to break the sound barrier, dude. Loosen up, have a beer, smoke a doob. Thank you Google for dishing up so handsomely.
