Did Stone Age people swim and dive just for the fun of it?
Surfer's ear is the common name for an exostosis or abnormal bone growth within the ear canal. Irritation from cold wind and water exposure causes the bone surrounding the ear canal to develop lumps of new bony growth which constrict the ear canal. The condition is not limited to surfing and can occur in any activity with cold, wet, windy conditions such as windsurfing, kayaking, sailing, jet skiing, kitesurfing and diving.
