Live long and prosper – the standard Vulcan salute, should be answered with: peace and long life, accompanied by the famous gesture with the palm held forward and upward, middle and ring finger parted, thumb extented.
Well, I hope he did have peace, and the long life of Leonard Nimoy ended now at age 83. Mr. Spock is no more. Sad for all Trekkies. I am sure, Sheldon from Big Bang Theory is out of his mind. But then again, these are all fictitious characters out of films and tv-series. No wonder, Mr. Nimoy called his autobiography I am not Spock.
