Dumbledore's Age

Just a thought, but...

I think Aging in the wizarding world has everything to do with your 
use of magic and where you live.  Dumbledore, McGonagall, et al all 
live and work at Hogwarts (of course I am assuming the living 
arrangements).  They live in an environment embued with magic.  They 
use powerful magic on a regular basis.  Could this use and where they 
live extend their lives?  I know this theory does not apply to 
Voldemort.  But in his case, he traveled quite a long time immersing 
himself in the Dark Arts.  Finding ways to extend his lifespan.  So 
therefore, half my theory works.  

So, I postulate, intense use of magic (not everyday use as in 
cleaning, or cooking, etc.) and the environment you live in can 
enhance the span of years.  That is why Dumbledore can be 150.

If you recall in SS, McGonagall is described as having black hair, 
not a mention of gray.  And in OotP she tells Umbridge she has been 
teaching at Hogwarts for 37 years.
