Recently, The Lancet published a case study that examined a 50-year-old patient who visited an ER after having a constant headache for two weeks. He had no signs of drug use or prior medical history indicating that he would be at risk — but he had been to a Motörhead show in the last month.

Surgeons removed a blood clot and the man has made a full recovery, but they linked his subdural hematoma to headbanging.

Doctors wrote in the study that “headbanging, with its brisk forward and backward acceleration and deceleration forces, led to rupturing of bridging veins causing haemorrhage…” and declared that the case “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.”

There you have it: evidence supported by medical doctors that Motörhead rocks.
