Bet you didn't know this?
The colours on a barbers pole usually reflected the blood and bandages used to clean up during bloodletting.
Patients grasped a rod or staff tightly to make their veins show. Then barbers cut open their arms and bled them. The red and white pole is still used to identify barbers.
