About seven years ago, a wall fell on me while I was shopping. I ended up with a traumatic brain injury (TBI) and severe PTSD. I lived in fear of any wall or shelf taller than me falling and crushing me. I refused to go outside without a bicycle helmet.
A major part of my recovery was to learn how to calculate the odds of a wall falling on me. Because one had, I assumed that it was a common occurrence. What I learned was that outside of construction work, it was rare.
I reviewed statistics on the various causes of TBIs. One third were from strokes, while another third were from falls. One sixth of TBIs were caused by car crashes. Of the remainder, the most came from sports injuries, such as being beaned by a flying hockey puck. Being crushed by a wall was an outlier. (These statistics had excluded military TBIs and gunshot victims.)
Therefore, when I go shopping, I repeat to myself how slim the odds are for being crushed by a wall. (I have since given up wearing a bicycle helmet.) It has become a habit of mine to assess the probability of being hit in the head. (I have no desire to reinjure my brain.)
One specific thing that I did which involved probability and my TBI:
I assessed whether the falling debris from the Chinese space station would hit me. When I heard the reports of this space station breaking up, I panicked. After finding out that the debris field would include where I lived, I had a severe PTSD attack. Therefore, I researched how much space debris actually do reach the ground. Most are burned up in the atmosphere upon re-entry. Since 1985, only two reported instances worldwide involved people. Therefore, the probability of any space debris hitting me was miniscule.
The picture of Moby Dick and the boat illustrates how remote wall falling actually is and the trauma I felt (and still feel).
