How old do humans live in Star Trek? Longer than we do, by quite a stretch. The average life expectancy appears to be between 110 and 120 years. Dr Leonard 'Bones' McCoy was 137 years old when he visited the Enterprise-D in the TNG pilot episode “Encounter At Farpoint”.
According to the Star Trek canon, the average human lifespan will reach 100 years during the early 22nd century. By the mid-24th century, the mean crested 120 years. This gradual increase in longevity is mostly thanks to advanced medical technology.
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.
Of the three characters, Spock is supossedly the oldest, being born in 2227 according to his fictional biography. McCoy was born in 2230, Kirk in 2233. Kirk is the youngest person to be made captain in Starfleet, so yes, he should seem younger than his colleagues.
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.
He was 24 at the start of TNG, and he celebrated his 30th birthday with the crew in the season 7 episode "Parallels." Michael Dorn was 35 when he began playing Worf and 42 when TNG ended, although he continued to play Worf in Star Trek: Deep Space Nine, creating the record for most Star Trek appearances.
Yes, Romulans have a maximum life expectancy of 250 years, but the average appears to be 200 to 230 years. The same is true for Vulcans, with the average being about 220 years. Spock's father, Sarek, lived to be 202 years. A good deal longer than his half-Vulcan son, Spock, who only lived to be 162 years old.
Kirk was born in 2233 which was canonized in both Star Trek (2009) and the TOS episode, “The Deadly Years,” where he said he was 34 years old, and that episode took place in 2267. Spock was born on stardate 2230.06, or in the Earth year of 2230 which was canonized on Star Trek: Beyond on Ambassador Spock's obituary.
The Vedala were discovered around the middle of the 23rd century (in the year 2268 or 2269), and are recognized by the Federation as the oldest surviving race capable of interstellar space travel. The Vedala space was encountered in Quadrant 1 near the Gamma 7A star system of the Milky Way Galaxy.
The character was not added to the cast of Star Trek: The Original Series until season 2, so his first appearance was in 2266 when he was 21. By the end of TOS, Chekov would have been 24, and his last appearance came with Star Trek: Generations in 2293 at the age of 48.
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.
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.
Changelings had an expected life span of at least several centuries. (DS9: "Emissary", "The Search, Part II") However, the female changeling noted that changelings were "timeless" and thus may never die of old age.
Jean-Luc Picard, as he is seen in 2401, is 96 ( or 106 in Beta Canon, or 2, depending on your perspective on cybernetics). He was born July 13, 2305, in La Barre France. He joined Starfleet in 2323, on his second attempt.
No exact lifespan has been given for Klingons, just approximates. In 2370, Odo observed that Kor "must be a hundred years old" and his "best friend," Koloth, was "probably a hundred and fifty years old." This observation was made over 100 years after their encounter with James Kirk.
There are instances of them living over 220 years. Having evolved on a fictional desert planet, Vulcans can survive without water for longer periods than humans. Vulcans can also go without sleep for as long as two weeks.
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?
Sadly, Spock died without ever siring an heir, and in Star Trek canon, neither Kirk nor Spock got to have descendants to carry on their adventures and save the galaxy.
Spock needed to return to Vulcan to marry T'Pring, who he had been bethrothed to since childhood. However, T'Pring had other plans and, instead of going through with the wedding, she handpicked Captain James T. Kirk (William Shatner) as her champion to fight Spock in kal-if-fee - a fight to the death.
Under stress, Vulcans could do without sleep for weeks. Tuvok once claimed that as a Vulcan he was capable of going without sleep for two weeks, although shortly after making this claim he was observed to fall asleep in the command chair after having gone a little over ten days without sleep.
There is no stated lifespan for the Borg; unless their ship or cube is destroyed they don't really die supposedly. Even the Borg Documentary doesn't have a lifespan for a Drone.
There are two possible origins for the Vulcans, neither of which are mutually exclusive. Some four billion years ago, a species of aliens known as the Primogenitors explored space and found no humanoid life. They seeded worlds with technology encouraging the evolution of people with a head, two legs and two arms.
