Although this is speculation on my part, I do think there are a lot of people around who are not necessarrily “suicidal” to the point where they are determined to end their lives, but are just “existing” rather than “living” and don’t care whether they live or die, and take increasingly risky behaviour – sometimes they get away with it, sometimes they don’t.
