Achilles Heel

So the myth goes something like this...

When Achilles was a baby, his mother, Thetis, dipped him in the river Stxy to make him immortal... or at least make his skin impenetrable. Unfortunately, she was dipping him while holding onto his heel and she forgot that one part of his body.

Achilles became a great warrior against the Trojans. He was an unstoppable force. That is, until an arrow was shot into his heel. This was the fall of Achilles.

- that's all
