Iceland is almost in the Arctic Circle and yet their schizophrenia prevalence is actually lower than the European average because they eat even more fish than the Japanese.

Finns have consistently the highest schizophrenia rates of any European people because they live so far north and yet, unlike the Scandinavians, they stupidly don't eat fish.
