Ok folks ACHILLE'S was a greek who was invunerable to attack due to being dipped into a magic potion when he was a baby (and no he didn't do Kebabs before anyone asks
)
The woman doing the dipping (his mother I believe) held him by one heel thus the potion didn't get to that bit and later he was defeated but some smart a** stabbing him in the heel
Hence "an Achilles heel" is now the term for any week point in the chain or any weekness that can or does cause failure
When the early Docs all got round the table to name the bits of the body they were all into Greek and Roman mythology (hence all the Latin and funny names) and they called the tendon down the back of the heel (wait for it ) The Achilles Tendon
So DK as your ankle is now a week spot in your body it is now "Your Achilles Heel" but when you had it crushed it wasn't
So Sprog was tecnicaly right but if you jump on the bike and crush it again you would be
That was long but worth it (to me anyway
)
