Warning labels and cautionary tales

I never really thought about the warning labels and cautions printed and tagged on various products and items we come across in our day to day living.  And then I heard someone talk about these warnings, and comparison to stories in the bible.  To think that these warnings exist because someone actually did or experienced these things.

Warning on a cup of coffee: Caution contents hot.
Warning on an iron: Do not iron your clothes while you are wearing them.
Warning on a blanket: Not to be used as protection from a tornado.
Warning on a superman cape: Cape does not enable user to fly.
Warning on a microwave oven: Do not use for drying your pets.
Warning on a sun-shield for your windshield: Do not drive with sun-shield in place.

Of course, it's easy to think that they were crazy to have made those choices or mistakes... but it is their mistakes and their choices that stop the rest of us from doing the same thing(s).
