Mostly, I agree with you Dave the Gnome. But in this case, I think it's comforting to know something about these things.

For instance, Donuel's opening post left the impression that it would be very easy for a terrorist to spread ebola virus throughout large segments of our population. After checking out a few facts about ebola virus, we now know that this would not be possible. So that's one less thing we need to be concerned about.
