Apparently, there is such a thing as rocking too hard—and it'll land you in the middle of a medical study that involves headbanging, brain bleeds and Lemmy if you're not careful!

A 50-year-old Mötorhead fan was suffering from some pretty brutal headaches for a month after he went to go see the metal gods live in Germany. Despite the fact that he hadn't bonked his head previously and had no history of substance abuse, the headaches wouldn't quit, and doctors at the Hannover Medical School found that the Mötorhead fan had a bleed in the right side of his brain. The doctors came to the conclusion that the dude had given himself the brain bleed from headbanging, but thankfully, they didn't judge—if anything, the applauded the guy for his intense appreciation for heavy metal!

From the study published by the Hannover Medical School study: "headbanging, with its brisk forward and backward acceleration and deceleration forces, led to rupturing of bridging veins causing hemorrhage." They also added that this particular instance "serves as evidence in support of Motörhead’s reputation as one of the most hardcore rock’n’roll acts on earth, if nothing else because of their contagious speed drive and the hazardous potential for headbanging fans to suffer brain injury." 

Furthermore: "We are not against headbanging," one of the doctors mentioned. "The risk of injury is very, very low. But I think if (our patient) had (gone) to a classical concert, this would not have happened...Rock & roll will never die. Heavy metal fans should rock on."

Indeed. \m/ \m/ \m/
