Works for me, too. 

I started noticing 30 years ago that there were several women in my workplace who rocked their grey hair, and looked a lot more stylish than the women trying to pretend they were still young by dying it, so when my turn came, I acted accordingly, and haven't regretted it. It is a nice silver. I get a good stylish cut, and I love it.

Mind you, this only works when you have passed the in-between stage where your hair just looks a mousy dirty brown. That's when I started to colour it to its previous colour. Once you have gone mostly grey though, I think going with it looks better, healthier, and yes, edgier. Plus I'm too lazy for all that root maintenance...
