    Age
In summary: The first man has aged more because on his journey, he moved more and experienced more events. The second man has aged less because he did not move as much and did not experience as many events.

What math is needed?

Geometry.

There is no such thing (physically-speaking) as "a path thru space-time" because space-time is math (geometry)

When two people born at the same time and place later have different ages, then something much more than mere math is afoot. And the only thing that differed about my people was their speeds.

Speed is just math, so it can't possibly be the reason.

(Just to show that your argument doesn't make the least bit of sense.)

The original question has been answered. Refusal to accept is not based on physics any longer. Thread closed.
