"For the sake of discussion, two billion of the world's population will die."

Jeanette. Wow - we have come to 'violent agreement'.
Hahahahaha! I can't believe you said that. You are about right. 2 billion people. IF you go with the WWIII scenario.

The only difference between you and me - maybe - is that your figure is a rough guess. Mine is calculated. But I guess I don't know - not sure where you got your "2 billion casualties" from. But we do come to the same final answer.

I will be driving through a bunch of countries soon ... many are on the "Not Recommended" travel list. Do you want me to send you the locations of any caves?
Do you prefer Your Cave with a basic no-frills Neanderthal design scheme?
Or do you do prefer Your Cave with air conditioning and stereo sound?
