How old was Spock when he died in real life?

Excuse me, I'm a bit confused about your question. Are you referring to the character of Mr. Spock from the popular science fiction television series and films, Star Trek? It's important to note that Mr. Spock, portrayed by actor Leonard Nimoy, is a fictional character and does not exist in real life. Therefore, he didn't actually die in real life. Perhaps you meant to ask about Leonard Nimoy's age when he passed away? If so, I believe he was 83 years old when he died. But please clarify if you were indeed referring to something else.
