There are about 7 Billion people living on planet Earth.........way too many.
I would make a wild estimate and assume that about 10% of the world's population is either neurotic, psychotic, psychopathic, addicted to drugs or alcohol, or just plain crazy. So about 700 million people fall into this category; a lot of crazies out there.
Sort of reminds me of the old Mill's Brothers song, "Paper Moon" ........"it's a Barnum and Bailey world, Just as phony as it can be............"
Have a silly day you all, and remember, if you could travel faster than the speed of light, you could go backwards in time.
