Reversed polarity

Recently I had to boost a battery. You know the type, like a car battery with positive and negative posts. 

The warning on the charger was clear. Red is positive and black is negative and of course there is a shock hazard if they are reversed. 

It did make me think and not just about what I was doing. There are so many people in this world that seem to get their wires crossed by behaving and thinking in ways that are shocking. They really need to take the time to read the instructions! 

I wonder if we all could be grounded better by paying attention to some basic rules?
