Scary or not scary? Wouldn't that be providence? Isn't this predestined? What is the size of a sample library of probability events for these seven or eight events? There is a psychology writer Keith Stanovich, in this is the psychology book, wrote: "4950 pairing events per day, multiplied by 1 year and 365 days, multiplied by 10 years, get 18067500 pairings." In short, in 10 years, if there are 6 connections that you think are rare matches, then there are 18,060,000 other pairing events that may also be rare matches. So, a rare match in your life, the probability of occurrence is 0.00000033. There are 6 rare matches that appear in 18,000,000 events, which do seem rare, but not surprising. Rare events do happen, and they are rare, but the factor of chance guarantees that it will happen. ”
