Did anyone else notice that in the DP article that talks about Umbridge 
becoming High Inquisitor, there is a quote from Lucius in it, and it lists his age 
next to his name!  He's listed there as 41 years old, which is right around 
the age I think Sirius, Lupin, Peter and Severus are (this is my assumption here 
obviously, figuring that James and Lily had Harry when they were around 25 or 
so).
Correct me if I'm wrong, but this is the first canonical confirmation of age 
we've received about *any* of the characters, aside from the schoolage kids, 
of course.  I know JKR has said in interviews that DD is up there around 150 or 
so (is that right?) and McGonagall is in her 70's (which figures well into 
the canonical knowledge that she's been teaching for 39 years).

But why bring up Lucius' age, specifically, and *not* bring up Sirius' or 
Lupin's etc??  What's so important about us knowing his age, if not to show it in 
relation to the old gang??

Any ideas?
