"Live Long and Prosper"
I like the heartfelt essense of this simple phrase. Everyone of my generation knows it from the TV series called Star Trek, which first aired in 1966. Click on the YouTube link below to watch Leonard Nimoy, the actor who played the Vulcan "Mr. Spock" in the show, explain how the Hebrew letter "shin" became the symbol of the official Vulcan greeting in 1967.
