I met a woman who owned a little souvenir store in New Mexico. In the 1940s she had been a secretary at a secret facility in nearby Los Alamos where scientists were working on the atomic bomb. "Yeah, those guys were never sure they wouldn't accidentally blowup the whole planet." she told me in a laughing manner. I bought some chili seasoning from her and was glad that while it might make my food a little hot, the earth would still be here.
