Juvenile primary lateral sclerosis (JPLS) , also known as primary lateral sclerois (PLSJ), is a rare genetic disorder, with a small number of reported cases, characterized by progressive weakness and stiffness of muscles in the arms, legs, and face. The disorder damages motor neurons, which are specialized nerve cells in the brain and spinal cord that control muscle movement.

—Horace Walpole (17171797)
“Wilful sterility is, from the standpoint of the nation, from the standpoint of the human race, the one sin for which the penalty is national death, race death; a sin for which there is no atonement.... No man, no woman, can shirk the primary duties of life, whether for love of ease and pleasure, or for any other cause, and retain his or her self-respect.”
