That sounds healthy...

Study predicts how tattoos will age

A couple of surprising things from the above article:

"Tattoos are incredibly popular worldwide with more than a third of 18-25 year olds in the US sporting at least one design," said Mr Eames.

That's a bigger proportion than I would have expected. Then there's this:

Tattoo inks are a suspension of water-insoluble particles, such as mercury, lead, cadmium and iron, which are injected under the skin using a needle.

Over time, these inks become dispersed as the cells which contain them die, divide or leave the body.

My, that sounds like a healthy past time: injecting your cells with poisonous metals. Are there ever any health consequences of that?

Hey, it seems the FDA has been looking into it since 2008. Seems they are taking their time about it, though.

What a pity. It would cause me some amusement if it turned out the FDA wanted to restrict tattooing somehow.
