A half-drunken Scotty beat up Klingons on Deep Space Station K-7. And before you go: "Wait, those are Augment Klingons so they'd be weaker and less physically imposing" remember that the whole point of introducing Human Augment DNA into the Klingon genome was to strengthen them and make them even more physically powerful than regular Klingons.
Maybe, we humans have been secretly increasing humanities average physical capabilities and ability to live longer over time.
Maybe the new average age of death for humans is in the 130-140's by the 24th century?
McCoy was 137 y/o and still moving about.
Picard was 94 y/o and still moving around just fine, if he didn't have that brain abnormality, we could've potentially seen him living even longer than McCoy.
Remember in ST:ENT, the average human officer had issues with Vulcan's due to the Strength differential.

Vulcans were, on average, three times physically stronger than Humans, and had considerably faster reflexes.
But by the time of ST:TNG the difference isn't as drastic as it used to be.
Maybe we're catching up gradually over time through slow genetic enhancements that are secretly being imparted on Children as they are born, part of a larger gradual conspiracy to raise humanities toughness to match all our fellow Federation members so that there is no physical capability gap along with the abilitiy to live longer?
