Surfing the net I stumbled across this:
Remember back in ’50s and early ’60s, when we set off something like 900 atomic bombs in Nevada? And how we just let the fallout blow wherever and it landed all over the eastern US? And how it wiped out life as we know it and all that was left from Colorado to the Atlantic were six-legged rats battling two-headed cockroaches in the glowing ruins?
Yeah. Exactly. So shut up with the panic already.
