I'm a geophysicist and all my earth science books when I was a student I had to give the wrong answer to get an A. We used to ridicule continental drift. It was something we laughed at. We learned of Marshall Kay's geosynclinal cycle which is a bunch of crap.
My very best friend died in a car accident when I was 16 years old. That was the hardest blow emotionally that I have ever had to endure. Suddenly you realize tomorrow might not come. Now I live by the motto 'Today is what I have.'
