Some disabled persons can’t walk, speak or do some of the most basic tasks to care for themselves. Several disorders cause this including cerebral palsy, autism (not to be confused with mental retardation, which sacrifices intelligence in favor of motor skills) and/or other damage of the nervous system due to toxins (Hg, Pb and/or others), medications, modern medicine and/or other agents.
Some of these individuals need to be fed, cleaned, showered, wiped clean after defecating or urinating (toilet, diaper or other medium) and/or helped with the most basic tasks to care for themselves. Some grow old with the faculties of little children or, in some cases, not much more than that of babies — never able to fend for themselves. Surprisingly (and stupidly) enough, caretakers (especially parents) need to apply for legal guardianship of their own adult children. These are the human pets.
