Yeah, Nickleanddime, I actually believe what you stated about getting your system's immunity increased by exposing it to 'bad stuff'. I won't say it always works. I know as a teen, I could lay down in a bed of poison oak and very seldom even get a little whelp or two. Then when I was in my fifties, I scratched myself on the wrist with a stiff vine and got my whole arm infected badly. I had evidently lost that immunity that I had from being around the stuff a lot. Now, I'm not sure, and afraid to find out how it would affect me! Doc said it could go either way. If I understand rightly, that's how most vaccines work. They expose the system to small amounts of a disease and it causes the system to become immune to it.
"Thunder Road" was a great movie. A lot of people today think it's a little too 'corny'. I still love it; try to watch it again every few years. Not very many movies that I can say that about! A couple of others come to mind: "Charley Varrick", with Walter Matthau and "Tequila Sunrise", with Mel Gibson.
Rumors of plagues have been around since I was old enough to know about them. No, I'm not saying there aren't going to be any; just that I'm not too worried about 'em. As for bioweapons, that would be my biggest concern. Nothing surprises me about any kind of weapons that can be used for war. I certainly hope not, but it wouldn't surprise me if we find that at sometime we have infected a people with something; or at least tried. The old saying 'all's fair in love and war' makes one think. The world is sadly watching the Gaza strip residents losing their lives. A lot of screaming is going on to stop it. A close friend of mine thinks that Israel should not be shelling/bombing the Strip because they have their 'iron dome' to protect them. She can't seem to see that her thoughts are--umm, stupid? As far as destroying the citizens of a country during a war, look what we did to Japan! No, I don't think we did wrong! We had to do something to stem the loss of our men's lives; so we did what we had to do. It was the only way to stop it. I don't believe in bioweapons; but there may come a time when we have to use something to save our freedom. I can't say that I see anything that I would condemn if it was the difference between our freedom and the loss of it.
