What amuses me about Hacker News: someone being sceptical about 'vampires' is met with responses like you see in this thread. Don't be so dismissive! Don't call them crazy! They may have a condition that doesn't show up on tests!
But just question the long term safety of nuclear reactors built on fault lines, or suggest anyone may have got cancer from radiation exposure, ever, and its just a wall of incredulity. Rubbish! Where's your proof! All the pro-nuclear science is beyond reproach!
Call me old fashioned, but these people are probably crazy, and radiation is probably dangerous. There's no bias quite like Hacker News bias...
