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