One of them IS younger. None of them GOT younger (aged in reverse).

Nobody aged in reverse, so nobody GOT younger. Both actually got older!

It is. The twins experience different amounts of spacetime.

The religion of relativity says the proper time thing is none other than spacetime (in length) divided by the speed of light.  This thing becomes a mythic quantity.  It is so ludicrous to talk about the proper time thing.  <shrug>

That isn't the definition of 'proper time' at all! Proper time is the 
time a clock always local to an observer keeps. Think of wristwatches 
that the traveling twins wear. The Lorentz transform isn't even involved 
in proper time!

Since a clock is always local to itself, proper time of a clock being 
what the clock displays is an excellent description, even if it's 
tautological.
