I had never heard of this before today and just chanced to read about it in a news item I was reading about obese kids. Wow, and I thought I had a weird reaction to the gold necklace I always wear (despite the fact that 3 months of not wearing it didn't clear it up). No longer will I scrub furiously at my neck! It is a pain (in the neck ) because it prevents me from wearing my hair up, so it gets pretty hot in the summer!

I shall watch with interest if it fades as I continue the journey DOWN!
