If you were standing on the railroad tracks and you saw a train bearing down on you at high speed, what would you do?  If your child was playing next to a cliff and you saw him chasing a ball towards the cliff, what would you do?  If burglaries and thefts were rising in your neighborhood, what would you do?  If a man confronted you on the street and demanded your money, what would you do?  In most cases you would act swiftly to get out of the way, save your child and take action to stop the crime and resist the robber from stealing your money.
