Nimoy signed all his tweets “LLAP” or “Live Long and Prosper,” his character’s catchphrase from the Star Trek series and films.
Nimoy had announced via Twitter last year that he had been diagnosed with COPD, a chronic respiratory disease caused by smoking that has no cure. He encouraged his followers to stop smoking.
