Grey first appeared on my chest, but not in an ordered fashion. I had one patch of it over my right side. Because everywhere else was so dark this looked like a bare patch from a distance. It almost looked like I'd shaved one area.
I've noticed recently that the hair on my stomach is losing its colour. However, yet again, it's doing so asymmetrically. The left side is fading away but the right side is staying dark. The change ends exactly on the ridge of hair that runs down the middle.
Odd thing, getting old.
