It's pretty amazing that we folks in our 70's are still alive. According to all the warning labels we read today, we shouldn't be. My grandparents bought us kids a toy xray machine for Christmas one year. It worked til it quit and we xrayed every place on us we could think of. Remember the xray machines in the shoe stores? How about the trucks spraying DDT to kill the mosquitoes, or the crop dusters dosing the fields with who knows what? Not to mention all the bomb testing that went on in those days or the wood preservatives we inhaled or who knows what else was out there. For some reason I'm feeling pretty invincible right now!
