I have heard of this.
It is supposed to work.
Awesome! Especially since I know about a hundred non-theater vets who changed spark plugs stateside for a few months and now have $1900/month PTSD. My favorite is the “Navy Seal” who was “dyed orange” from his work with the Air Force “killing women and children.” Had the tattoo and everything. No BUDS class - too top secret for that stuff... But always the $2000/month from the taxpayer.
