That's an interesting question. He still has some magic about him
(thank you the person who answered about removing Draco's magic, it makes
sense!), so does that mean he's aging at wizard speed rather than Muggle
speed? Is he really over 60? (and if Flanel is that old, does that make
Dumbledore the same age?) If that's the case, then how old really are
the other teachers? (Seems to think Madame T is like 120! A wizened old
hag leaning over a crystal ball!)
