One of the issues not really addressed in TOS is average human lifespan in the future. Today people on average stay younger and more vital longer than even fifty years ago. 50 is the new 40 and 60 is the new 50. If this trend were to continue (not necessarily in a linear manner) than humans might live about 20-30 years longer on average than they do today or the average in the ‘60s.
The one time that issue might have been apparent was in “The Deadly Years.” By the standards of the average lifespan in the mid 20th century at the rate our heroes were aging I would have expected them to be dead in short order. But if the average lifespan in the 23rd century were longer than that window of survival would have been greater.
And finally in TNG’s “Encounter At Farpoint” we see McCoy at 137. Maybe he was an exception, but it did suggest humans of the 23rd century are expected to live longer on average than today. And that was bolstered by Picard being physically and mentally vital and in command while in his 60s.
