Because cutting hair and limbs is basically the same thing
Context: During the Middle Ages, medical practice was sharply divided between university-educated physicians and barber-surgeons whose mastery of sharp tools made them the primary practitioners of physical medicine. Armed with razors, saws, and shears, barbers expanded their services beyond hair cutting and shaving to handle minor procedures, tooth extractions, bloodletting, and urgent field surgical interventions such as limb amputations. Because medieval surgery lacked anesthesia and sterile environments, speed and mechanical dexterity were paramount to prevent fatal shock and blood loss, making the barber's practiced hand with blades the most reliable resource available. This dual identity persisted for centuries, memorialized today by the traditional red-and-white barber pole, which originally represented the bloodied and clean bandages wrapped around a pole used by patients to swell their veins during phlebotomy. #history
