Stylebook again

People who are "rapidly aging":

Bilbo Baggins in Lord of the Rings
Dorian Gray when his portrait is destroyed
The twin brother of a spaceman travelling at 99% of the speed of light, from the spaceman's frame of reference.

People who are not "rapidly aging":

The population of Europe
The population of Japan

Every hack writer on demographics commits this solecism, but that doesn't make it OK.

  1. Absent gravitational time dilation, I believe you'll find that your twin is in fact aging slowly, when you look at him out the window of your personal spacecraft.

    I'd say you were referring to a special case, but that would confuse.

  2. "Absent gravitational time dilation" is a pretty big ask though isn't it?

  3. "General Relativity: we're all in it together"

  4. If we can ask one personal spacecraft, I see no reason we can't ask at least a space suit for the twin.

    Seems a lot less to ask than a planet, to me, but then maybe you just take a planet for granted.
