"Just 50 years ago, people treated the shiny liquid metal like a toy. Sadly, I’ll never experience the strange sensation of sticking my entire arm into a barrel of mercury, as kids once did during factory tours. Today mercury is considered a horrific poison, so bad that schools are evacuated for a broken thermometer.
Of course, mercury didn’t become more poisonous; we just learned more about it, including the fact that breathing its vapors can lead to brain damage."

Anyone thought that it could be applied to x-rays? Maybe some day in the future, some guy will say that ppl in the past use x-rays to blast at poor sick patients. "It's not that x-rays got more dangerous, we just learnt more about it, including the fact that x-rays cause spontaneous cell damage."
-Oh well, that's just my ponder, no worries right now. What you don't know won't kill you...
