Fully 80% of illness is functional and can be effectively treated by any talented healer who displays warmth, interest, and compassion regardless of whether has finished grammar school. Another 10% of illness if wholly incurable. That leaves only 10% in which scientific medicine - at considerable cost - has any value at all.
This makes me think about Jesus of Nazareth - carpenter, teacher, healer. This helps us to better understand the miracles of his healing - which were directly linked to the miracle of his warmth, interest, and compassion.
