47. Understand the difference between risk and dread

It just might save your life. As an example, declining to fly to a distant destination for fear of a terrorist event and instead driving that long distance. Driving per mile is much more dangerous than flying per mile. You are now exposed to more risk of death than the dreaded terrorist attack. What is one to do? Another example might be vaccines and their side effects. The risk of the side-effects is much less than the illness that the vaccine prevents. There is no dread usually in smoking, but smoking is very dangerous to your health. Your choice, again.
