paying attention

do  you pay attention to what's going on around you?  really?  would you notice if the person you were talking to suddenly changed into someone else?  we all like to think so, don't we?
derren brown did a person swap experiment.  when i watched it, i couldn't believe people's responses.  take a look for yourself...

i was especially dumbfounded by the last example!  this is something i hope never happens with me... that i am always aware of what is going on around me.  pay attention to your surroundings at all times...

happy day.....
