Originally a jewish saying which was commandeered by the famous television series "Star Trek" when jewish actor Leonard Nimoy used it as the Vulcan salute. It's now used as way for us nerds and sci-fi lovers to say goodbye in a different, more permanent way.
Friend moving away to another country - "i'm gonna miss you, man". Nerd - "Live long and prosper"
Leonard Nimoy was famous for saying, "Live long and prosper." He himself seems to have accomplished that thanks to his good looks and pleasant personality, but I wish he would have explained to all of us about how to do it ourselves.
