Hello,

I thought I'd come out of lurking to ask a quick question:

If we take Dumbledore and Marchbanks as a guideline for wizard
lifespans, then the average wizard life should last about 200 years.
Yet none of the Blacks in the family tree lived anywhere close to that
long (the oldest seem to have lived for about 80 years or so, which is
barely above half of Dumbledore's age). So what happened to them? Why
did all of the members of this distinguished, pureblood family die far
before their time? Should we go back to the drawing board at
determining wizarding lifespans, is something more sinister going on
here (perhaps hinting at a line of servitude to angry dark lords
(Grindelwald?)?
