Depends on how you define worst.
Most dangerous? Most contagious? Most deaths? Biggest impact on society?
I believe that THE most contagious, most dangerous and biggest killer is not a health virus.
It is FEAR.
Fear can save your life when you are in danger.
Fight or flight stuff.
Walter Cannon, chairman of Harvard University's physiology department from 1906 to 1942, originally describes this phenomenon..."The hormone, adrenaline, activated by the autonomic nervous system, sends signals to various parts of the body to activate the fight-or-flight response. Increasing heart rate and blood flow to the muscles, dilating pupils, and slowing digestion."
Fear can also cause the opposite. It's called quiescence. Or, "playing possum."
And it can also save your life.
Quiescence saved missionary David Livingstone's life. In Africa, when a lion grabbed him in its jaws, he went limb. He reported that he felt no pain, even "a kind of dreaminess." The lion dropped him and moved on.
We are not underestimating the impact of the Coronavirus in any way. The death toll has now reached more than 3,000 in the United States. This is more people than we lost during 9/11. I am a firm believer we have to be smart and follow the rules. Everyone should practice social distancing, wash our hands constantly, and stay home (please, STAY HOME).
Fear can also steal your life away. Anxiety, worry, fretting, consternation... and panic.
Stealing your confidence. Stealing your courage. Stealing your heart. Stealing your will to really live.
William Wallace, made famous in the movie, Braveheart, was purported to have said, "Every man dies, not every man really lives.
Fear can steal the heart of a nation. Fear has currently taken over our nation during this scary pandemic. But again, if everyone will follow the rules our government is telling us to do, we will come out of this on the other side together.
In crisis, we need confident, courageous, committed men and women with the WILL to live... and overcome!
This virus will pass. Wash your hands, keep your distance from others, avoid touching your face and help those in need.
Another virus will come. So will other disasters.
Resist the call to fear.
It's time for COURAGE!
