Trivia: ACHILLES HEEL

In Greek mythology Thetis dipped her son Achilles in the mythical River Styx. Anyone who was immersed in the river became invulnerable. However Thetis held Achilles by his heel. Since her hand covered this part of his body the water did not touch it and so it remained vulnerable. Achilles was eventually killed when Paris of Troy fired an arrow at him and it hit his heel.
