It's Friday which means a new 'Code Name: Hunter' page. Man, that gray hair comes in quickly, doesn't it? *laughs* I started seeing gray in my hair earlier this year. The number of gray strands that have popped up over the last six months is surprising. It seems every time I look in the mirror I see a few more. I'm only in my mid-thirties! I'm too young for this nonsense!
As for Emily's slower aging no, she doesn't have any abilities with magic. Mass exposure to magic has been known to slow down the aging process in non-mages. As for retiring, neither Emily nor Allen have shown any real interest in doing so at this time.
