Spock would have been in his mid-30s during the events of The Original Series. In human years, he would be roughly in his sixties. However, Vulcans have extremely long lifespans compared to humans and it isn't unusual for Vulcans to live to 200 years of age even though humans and Vulcans mature at about the same age.
Sadly, Spock died of natural causes in New Vulcan in 2263 during the events of Star Trek Beyond. Though Leonard Nimoy's version of the Vulcan died only 33 years after his date of birth in the Prime timeline, Ambassador Spock was 162 years old chronologically when he passed away in the Kelvin timeline.
It says that Spock was born on Stardate 2230.6 and died on Stardate 2263.02. That does make it look like Spock was 33 when he died (the same age as the emo-Spock that is looking at that display). Spock was born in 2230 and died in 2263 so this did technically make him 33.
Lifespan. The Vulcan lifespan is longer than that of humans. Vulcans have been known to live over 200 years, though there has been cases where 250 or 300 can occur. After reaching adulthood, the aging process of Vulcans slowed a great deal.
Memory Alpha notes that there is no canonical maximum estimate for Klingon lifespans, but several Klingons are known to have exceed a century, and some may have made it past 150 (earyh) years. That makes them pretty comparable to 24th century humans.
No canonical children have been mentioned for Spock. Drafts of the scripts for Star Treks III and IV hinted that the rejuvenated Spock impregnated Saavik during his accelerated Pon Farr, but this was not referenced in the script as filmed.
LLAP' – Leonard Nimoy. The beloved Star Trek actor delivered this final thought to the Twittersphere a few days before his death in 2015. 'LLAP' is shorthand for 'Live long and prosper', the classic catchphrase of Nimoy's TV alter-ego, Spock.
He entered the alternate reality at age 157 and stayed alive for 5 years (http://memory-alpha.wikia.com/wiki/Spock#Involvement_in_the_alternate_reality) and he died due to natural causes.
Spock Died in Every Version of the Star Trek II Script
The filming of the first movie was a disaster, and so Nimoy wanted no more to do with Spock or Star Trek. Jack B. Sowards wrote his first draft for Wrath of Khan with Spock in the story -- and killed him at the end of the first act.
As Spock explained to Kirk in Star Trek: TOS, his union with T'Pring was "less than a marriage but more than a bethrothal." Indeed, Spock was meant to finally undergo the koon-ut-kal-if-fee marriage ritual with T'Pring in "Amok Time" before she invoked her right to have Spock fight to the death for her.
The beloved Vulcan's full name is officially S'Chn T'Gai Spock. The name actually comes from a popular fan work-turned novel for The Original Series in Barbara Hambly's Ishmael which was published in 1985.
Michael is about 4 years older than Spock, but curiously, Sybok was already gone when the young Burnham moved to Vulcan. Sybok is never mentioned in any of Michael and Spock's flashbacks to their childhood on Star Trek: Discovery, but was Burnham aware that Spock had an older half-brother?
Every seven years, Vulcan males and females experience an overpowering hormone imbalance known as pon farr. Once triggered, a Vulcan must have sexual intercourse with someone or the chemical imbalance may cause insanity, loss of self-control, and death.
Spock has always had a complicated family dynamic, but his older half-brother Sybok is especially troublesome. While Sarek, Amanda, and Michael Burnham are all heroes, Sybok tends to be more villainous. Audiences were first surprised by Sybok's existence in the film Star Trek V: The Final Frontier.
Chapel was the one who had a crush on Spock, but as Spock suppressed his emotions most of the time, she never was able to get far. Spock's only real love, if you can call it that, was Leila Kalomi in the Season 1 episode 24 called “This Side of Paradise”.
Among the non-immortal humanoid aliens, the longest-lived appear to be El-Aurians (e.g. Guinan) who have lifespans of 750 years or more. Among Trills, the humanoid host lives as long as a human, but the worm-like symbiont lives at least 400 years, apparently. After that, Vulcans and Romulans are about 200 years.
So, Spock is older than Kirk, but only by 3 years. I don't know about you, but much past college I'd stop noticing a 3 year age difference, however you are technically correct (the best kind of correct). Kirk entered Starfleet Academy in 2252, and graduated only a year or two later in 2253 or 2254.
Why did William Shatner go to Leonard Nimoy's funeral?
However, Shatner, 91, remains unrepentant about the decision, telling Variety: “When Leonard Nimoy died a few years ago, his funeral was on a Sunday. His death was very sudden, and I had obligated myself to go to Mar-a-Lago for a Red Cross fundraiser. I was one of the celebrities raising money.
Spock quickly perishes, and, with his final breaths, says to Kirk, “Don't grieve, Admiral. It is logical. The needs of the many outweigh . . .” Kirk finishes for him, “The needs of the few.” Spock replies, “Or the one.”
At the beginning of the third movie, we learn that Spock and Uhura decided to break up, after Spock mentioned his dilemma about going back to New Vulcan, getting married and helping to rebuild instead of going through his Starfleet carrier.
Sarek was married twice, and had two sons. Prior to his first marriage, he had a relationship with a Vulcan princess which produced Sarek's first son Sybok, a character not developed until the fifth feature film in the late 1980s. Sarek later married Amanda Grayson, a native of the planet Earth, with whom he had Spock.
