It's sad most folks don't react but not everyone has that ability to react to the situation - fight or flight, most people will flight.. It happens all the time, look at the Aurora, CO. shootings, Columbine and others. In the theater shootings one guy stated the gunman was practically standing next to him while he laid on the floor. Why didn't he kick the guy in the family jewels? Jump up and knock him off balance? Again, not everyone has the ability to react to the situation.
Correct...but we here hear it all the time. It's all about Mindset.
And as has been observed here and on other posts, most are not geared up to be living with that outlook.
Much of the reason, not blame because it is still each individual's responsibility for their thinking, is that our technology has allowed us to insulate ourselves from the harsh realities of nature. We were able to stop fighting the environment tooth and nail and, instead, we have "modified" the environment and have built a shield to keep it out.
What folks don't realize how thin and fragile that shield can be.
My view.. "The world is a snarling beast waiting for an opening to be at your throat and clawing your guts." And all it takes is some natural disaster, "flash mob", mugger or even a moment of carelessness to be in a struggle for your life. Be ready for it.
Most folks aren't.
"It's a jungle out there." Tough but true reality is that for one organism to survive another must die.
As I've said before "We survived because we became the most vicious, cunning, intelligent and dangerous animal on this planet. Let us not forget our heritage."
