I was eating lunch today when my friend looked up from his phone as said "Have you heard the news about Leonard Nimoy?" I knew immediately that he had died. I knew his health had been declining and that it was only a matter of time. I've enjoyed him in everything he's been in, and I'm glad that I was unable to find anyone online who had anything but positive things to say about him. He was a great actor and a great man.
Looking at his Twitter feed, it would seem that he knew his time was coming:
Each tweet is signed "LLAP," which means "Live Long and Prosper." He certainly did.
