Help!

Do you think I should get this looked at?

Some people scare me with their lack of common sense.  I love this picture, it says a lot about how I feel about common sense, or the lack of.  Have you every wondered how some people survive through the day? If you have common sense, you believe certain things are the things that everybody knows.  However, you will find yourself saying, "How did she not know that?" or "Why would he do that?"  You think everyone knows.  Well . . . they don't!!!! And it drives me crazy!!!!!    For instance, Everyone knows you do NOT turn on your hair dryer while you are still in the bathtub, right?

A study in Berlin investigated 41 cases of death by electrocution from 1995 - 1999.  A hair dryer was the culprit in 75% of the cases.  Where is the common sense?  How do you help people find it? 

 Ta for now.
