Wizard Lifespan

Well - a wizard's lifespan is magically altered, a magic that's 
unaware, wandless magic. As magic goes, it has more to do with what 
the wizard wants, rather than with maths.

A child wants to grow up - but once an adult, aging doesn't have many 
benefits... (physical age).

So um- while aging/growing has benefits, a child grows and learns 
slightly faster with the help of magic (but, since their powers 
aren't that great yet, not by much - ending to adulthood at 17).
Adults, around certain age, don't wish to age physically - and as 
their powers are greater, they're able to slow physical aging for 
longer. So - Molly is fertile still at 60-70 etc..
