Ya I think distance can help.
My last Uncle died last fall at 90 years old.
Milbert Walker. I put his WWII stories on youtube
I saw Milbert on his death bed and he kept saluting in his sleep, and they had to put arm protectors on him because he was bruising himself from saluting.
He always had knight meres from WWII. He went to Germany and Africa and Italy and several countries during WWII. Doing the actual killing. Many soldiers didn't do killing, but it haunted Milbert his whole life.
