Questions need to be invariant over a lifetime.

Could we have 16 bits for latitude and longitude of birthplace? That gives almost 1 degree resolution on the surface of the earth, enough to narrow it down to a particular city.

If you really want a unique identifier, then the 33 bits should be
extended to 36 bits and one bit assigned to alive/dead status. TODO:
figure out how to handle cryonic suspension, people declared legally
dead who later turn up alive, and new births. (Neither zombies nor
ghosts will be implemented because they aren't real.)
