Etymology of sanity and sanitation
#
Sanity and sanitation share a root in sanitas (health), but their paths diverge in practice. Sanity targets inner health, while sanitation fixes external conditions. The punchline: you don't get mental wellbeing by washing hands alone-you need reliable services, housing, and care. Elevate universal basic services, and sanitation becomes part of a humane, sane society.
