I read online that some people are afraid of the number 211

.

"Somehow I developed the fear of dying while rading a book between pages 208-211, the odds of death increasing with each number- this has generallized into a fear og the number 211. When I pass a digital clock around 2:11 I nervously check to see if the fatal number has passed or not and if it is 2:11 I nervously wait untill the danger is passed at 2:12"
