In our current society, we are often distracted from our everyday lives by outside stimulus such as children, music in the car, and perhaps worst of all, the cell phone. This task fixation is potentially dangerous. We can walk into traffic, get into an accident, or fail to notice other dangerous situations.
Awareness can be the most effective way to stay safe. By identifying a danger early, you can avoid it completely. We all have instincts build in to detect danger, but often they need a tune-up.
You can tune your senses by making it a game. See how many exits there are out of the room (make it really interesting by adding in the staff exit door you saw outside and figure out how to get to that door). Notice how many young males (prime crime demographic) are around. Spot the most suspicious person and justify why they fit that category. Pretend to be the predator and select the person you would rob (this gives you an idea of actions you should avoid). Work hard to find something you never noticed on your daily commute. Playing against your significant other can make it a fun activity and keep you aware of your surroundings.
Once you are attuned to your surroundings, you are more able to make decisions that will ultimately keep you safe.
