Ok so DD is like 150 right? (But Harry doesn't know this yet.) 

And is this possibility of lifespan different for those who are half-
blooded, or is it all wizards that have this longevity?

Also, can a phoenix ever die? I just got that newt scamander book and 
it said they have (i'm not quoting) an extensive lifespan so do they 
ever die, or do they just keep existing?
