How could you possibly know this?
For example: Why is it that, as a rule of thumb, people that make money make it in real estate?
Why is it that all the pictures of the sun are orange but the sun is not orange?
Why exactly, is it that people prefer gas ranges to electric ranges?
Why is it that horoscopes are demonstrably false but thermodynamics is demonstrably true?
Why is it that heat rises but it's cold in the mountains?
I have the answers but you have only the questions.
