These need to be questions that are invariant over a lifetime: - Were you born in the northern hemisphere or southern? $2^{33}$ is sufficient for those alive

These need to be questions that are invariant over a lifetime:
- Were you born in the northern hemisphere or southern?
$2^{33}$ is sufficient for those alive now, but the human population is a dynamic function. Set a bit when the person dies?
- azatris 13y agoThe Northern Hemisphere has roughly 90% of the population[1]. That is far from 50% what we should be looking for. [1]: http://en.wikipedia.org/wiki/Northern_Hemisphere http://en.wikipedia.org/wiki/Northern_Hemisphere
- sgustard 13y agoAre you born above or below the tropic of cancer then: replace with whatever latitude separates humans into equal groups.
- splike 13y agoThis make other questions based on geography useless (as in the second question). Thats not to say the already given second question is better than your one
- GuiA 13y agoEven with questions invariant over a lifetime, edge cases like identical twins (same gender, same age, likely same upbringing, etc) are likely to mess with it.
