Hi Anons, just thought I'd share this thought with you.
Back in colledge (1990) I worked as a maintenance guy in an old folks home in the evenings.
I got to know a gentlemen who was 99 years old and fought in WWI
From time to time I would walk past his room in the night and he would be having terrible night dreams/delirium and would be screaming.
The thing he would scream most often was Gas! Gas! Gas! oh God Gas!
As a punk GenX, never to serve, young man, I have NEVER forgotten that.
WWI was horror beyond all horrors!
