That's why you have brain, so you don't buy/get stuff you don't need. However, It seems that people stopped using that brain since 24/7 news channels.
I don't have any masks, and liquid whatever soaps, nothing, and neither does anyone I ever knew in my life. EVER. All generations, and we're all alive and kickin'. In fact, I can with certainty say that we here from Balkan are healthier then people with all this high tech soaps and masks and the rest of it. You know why ? Because we don't go to hospitals for every meaningless symptom and don't panic, in fact, don't think about that stuff at all. If I die I die. Fuck it. I'm not gonna live my life buying gas masks and walking around with one. I for my self, can say, I know without news propaganda/sensationalism/whatever when and what to do, and if I'm mistaken, I don't care. I'm gonna die anyway. I abandoned the notion that I'm important so important. In the grand scheme of things, only thing that matters is my relationships with people in the now.
Regarding this nuclear disaster topic, or whatever you want to label it as, same rule applies. Common sense and thinking is all everyone need. Spend a month learning, informing yourself if you think it's important for your situation (where you live etc) to know.
Read 50 different media sources, including the conspiracy theorists, why not ? Are you closed minded skeptic or open minded skeptic ? After you do all that, you'll know what to do. Relying on media to care for you is retarded. Think and act for yourself, stop being a pussy.
