Calculate 7 pm Sydney time to what time it was in Greenwich, England at that time then do the same with Vancouver, whichever was earlier is older. Greenwich is where the time zones kind of "start" if you get what I mean.
 
But what if one was born in space and lived on the moon for his first 10 years?
That's easy. The one in space would be ever so slightly older, due to the Earth having a greater gravitational field than the Moon.
 
the aussie, because we're awesome.
anyways who cares, we can drink at 18 in aus, so the vancouverite is screwed either way:D

In Canada, you can drink at 19 (18 in Quebec).... one year is hardly a screwing. And we have better beer.... it's worth the wait! Or get a fake ID, like I did.


I say cut one of their arms off on each of them and count the rings.
