I had never heard that the "assume you're already dead" tactic was used by anyone. I can vouch that it works, I was born with several heart defects and spent so much time as a child and through my early 20s going in to surgeries and procedures with uncertain outcomes that being "already dead" has been my thing, a kind of "I was born already dead" mental headspace, I still think that way effectively 100% of the time and as a result I'm pretty hard to be derailed by mundane problems, fears and slights that seem to get under the skin of others. I wonder why they don't continue that mindset when they get home, I wonder if any military psychologists have identified downsides? A few different periods of my life I've gone to therapists and they don't seem to know care about that headspace once they carefully confirmed that I'm neither suicidal or a high risk taking individual.
