Why Does Hair Turn Gray as You Age?

Taking the helmet off works.     Last time I got pulled over I passed a cop and another vehicle doing 90 mph.  We started to have a different conversation after I took my helmet off and he looked at my Strada.  Not a crouch rocket and not a HD.  ATGATT rider that's older.

My hair has always been thin, now it is really thin.

When I met my husband, he was only 19 and had a full head of salt and peppa. I found my first at about 25 and it was already a few years old as it was over a foot long. Now he's still got only slightly more salt and I'm half salty. Our 17 year old son is just like his papa.
