"Must remember: bright flash = don't look out the windows."

Unfortunately, it happens way too fast for you to be protected by your own reactions. It's instantaneous ... whatever you are doing at that moment in time - that's what you get. If you are facing the window and looking out - then you are probably blind and certain;y impaled by broken glass. Not to mention that the shock wave will demolish your building anyway.

With a nuclear bomb ... the two best places to be are
(1) Standing right beside it
(2) 100 miles away
Either way you've got nothing to worry about :-)
