Well, Maybe If He Spent More Time With Them

From the New York Daily News:
It's not the job turning President Obama gray - it's his daughters.
First Lady Michelle Obama joked in an interview Tuesday that watching his two daughters - 14-year-old Malia and 11-year-old Sasha - grow up and approach their teenage years is a scary thing for the president.
"There's nothing like the look on his face when Malia dresses up for a party and she's heading out," Obama said on "Good Morning America."
"She walks past him," Obama said, "and you can see his face sort of just drop a little bit. It's like, 'who was that?'"
And that hair that's gotten very noticeably grayer since his first inauguration?
"People think the gray is from his job," the first lady joked. "It's from his children."

Obama, short of physically abusing his kids is one of the worst dad's possible.  He won't go on vacation with them, he goes to Las Vegas and other cities to bang his mistress(es) and the only time you see Obama with his kids, is in photo shoots.
No, Obama is not a father of the year candidate and maybe he is getting grey because of guilt.  But then he is so narcissist, he feels no shame or guilt.
