Question: Even though Matthew has never expressed any desire to endanger himself, whenever he feels stressed or overwhelmed, he makes plans to visit a certain deep spot that he has visited many times before. Once there, he decides to plunge into the profound depth. The astonishing thing is that he has never been hurt because of his dive, and he even says he feels much better afterwards. What is happening here, and why has he never been injured or, even worse, killed as a result of his risky behavior, if he isn't trying to harm himself?
