I don't know of any particular, but I can imagine cultures
where people don't have first or last names. For sure alot of
people on this earth don't have a mailing address that'd fit
into the "usual" schema. Don't make the schema too scattered
just to avoid NULLs. Wether you like them or not doesn't
matter, use them where they are handy.
