    On a reread of GoF I am at the part where Harry falls into 
Dumbledore's pensieve. He sees Dumbledore looking much like he does 
now but Karkaroff and the Crouches looking younger. My thinking is 
this the more powerful a wizard you are the longer you live. Not 
because you can do spells or charms on yourself but because your 
ability makes you stronger. The more abilities you have the stronger 
your physical attributes are and the longer you live. Dumbledore is 
the oldest wizard alive that we know of, his friend and previous 
partner lived to be about 620(?)and he used the stone to achieve 
this. But we don't hear of any other o-o-o-old wizards just, by 
Muggle standards, mainly middle aged wizards. Does anyone else think 
this? Like maybe being a very powerful wizard or witch slows down 
your aging process?
