Memories! That’s me, together with several cohorts, somewhere around 1970. An engineering recruitment ad for Taylor Instruments, where I first worked as an engineer.
If you’re as old as me you’ll remember, “Don’t trust anyone over thirty.” Attributed to political activist Jack Weinberg in 1964, it became a slogan in the integration/free speech/antiwar movements in the ‘60s and ’70s.
Here’s an earlier version. “Every man over 40 is a scoundrel.” (George Bernard Shaw in an appendix of his play, Man and Superman,1903).
