My dad flew 32 missions over Germany. He watched men die. 80% of his cohort did not return. He expected to die and made his peace with it. He told me once that when he returned home, he was struck by the trivial problems people had and obsessed over. After all, they weren't flying a mission tomorrow with near certain death.

He said whenever he felt down, he'd recall the men that never had a chance to grow old, and his problems would melt away.
