I am a *bad Catlady* for forgetting to include this in my previous 
post.

I have mentioned before my theory of wizarding age, according to 
which wizarding folk age the same as Muggles until age 20 (nice 
round number) or 21 (magically important number) and then half the 
rate of Muggles.

I mentioned it on FictionAlley Park and the extraordinarily brilliant 
and insightful Minerva McTabby explained her theory, which is 
harder to compute than mine but seems more accurate:

>From then, they age at one-third the rate of Muggles until around 
the age of 100. After that, they age at half the rate of Muggles. And 
it's as rare for wizard folk to reach the age of 200 as it is for 
Muggles to reach 100. >>

My examples and her examples:

mine: Dumbledore in Cos flashback = 100 // 100 - 20 = 80. 
// 80 / 2 = 40. // 40 + 20 = 60. // Dumbledore as auburn-haired 
Transfiguation professor appeared to be 60 to a Muggle. 

hers: Albus Dumbledore in the diary in CoS, aged 100. 
100 - 25 = 75 
75 / 3 = 25 
25 + 25 = 50 
He appears around 50 to Harry through Tom's memories. 

mine: Dumbledore at 150. // 150 - 20 = 130 // 130 / 2 = 65. 
//65 + 20 = 85.

hers: Dumbledore, aged 150 - if he's been aging at half the Muggle 
rate for the past 50 years, that adds 25 years to his appearance in 
the 1940s flashback, making him look about 75 in canon. 

mine: McGonagall = 70. // 70 - 20 = 50. // 50 / 2 = 25. 
// 25 + 20 = 45. // McGonagall appears to be 45 to a Muggle, 
therefore casting Maggie Smith requires willing suspension of 
disbelief. 

hers: McGonagall, aged 70. 
70 - 25 = 45 
45 / 3 = 15 
15 + 25 = 40 
Fits in with image of McG in the drawings by JKR.
