The war pix from the 50s and 60s had the actors in them who’d fought in WWII and some in Korea.
They had flint.
Boy, they sure did. That is one of the reasons I find the snowflakes we see now in our young men to be so offensive.
Perhaps if we didn't have men and women of that generation to compare them to, the Snowflakes of today wouldn't seem so egregiously effeminate, delicate, and weak.
Perhaps, but...probably not.
