Rabies is a disease humans may get from being bitten by an animal infected with the rabies virus. Rabies has been recognized for over 4,000 years.

An Achilles heel is a weakness in spite of overall strength, which can actually or potentially lead to downfall. While the mythological origin refers to a physical vulnerability, idiomatic references to other attributes or qualities that can lead to downfall are common. Synonyms.
The Achilles tendon is an important part of the leg. It is located just behind and above the heel. It joins the heel bone to the calf muscles. Its function is to help in bending the foot downwards at the ankle (this movement is called plantar flexion). If the Achilles tendon is torn, this is called an Achilles tendon rupture. The tear may be either partial or complete. In a partial tear, the tendon is partly torn but still joined to the calf muscle.
