So I currently have 4 gray hairs. When I get 10 I'm dying my hair as black as night. Have you colored your hair?
I used to do it at home (not professionally) but I'm going to stop and let the grey hair take over. Grey hair is pretty trendy now. 
I'm gonna pass on the Gray's. I blame them on my wife. 
And I'm sure she blames hers on you! Funny how gray hair is associated with age AND stress. Which is it?
