- It can hardly be said that the human knee is well designed for kneeling.
- Prolonged kneeling can lead to an expansion of the bursa in front of the
- patella, a condition known as housemaid's knee. (Perhaps that's why house-
- maids are almost extinct.)
-
- Likewise, there's a design flaw in the human elbow. At the knob on the
- lower end of the humerus the ulnar nerve is exposed just under the skin.
- A sharp blow by a hard object causes that numbing, painful sensation called
- "striking the funny bone" (a pun on the name of the bone).

-
- There are some additional design flaws that appear in the manufacturing
- process of humans: the fetal lanugo, the grasping reflex, the Moro reflex,
- and the fontanelles. Even the adult human skull is too thin to provide
- adequate protection to the gigantic brain and the absence of brow ridges
- leaves the eyes poorly protected.
-
- When can we expect issuance of the recall notice?
