I'm the grandson of a WW2 vet so I've always been interested in this time period. I also had the good fortune to do some video production work with a survivors shooting a series of interviews. It's so inspiring how they fought so hard and didn't give up even facing certain death. This answer really sticks out to me as well.
I was too busy trying to live and prevent dying. Suicide never entered my thoughts.
Life is too precious give up. I encourage people to do everything possible to prolong life.
There are always ways to live a life that matters, it's never too late.
