I would really like to know who those experts who always comment on the people on the show. It gets kind of frustrating to hear: Our experts say that the probability of TEOTWAWKI (take your pick here) is highly unlikely or hasn't happened in the modern age (whatever that is). I would like to know what their bonifides are. Wonder why they always down play the potential for a problem? Inquiring minds wanna know, or at least I would.
