I read this article yesterday as well.
I've thought about this tattoo preservation in the past ... my organ donor card has "skin" as the exception ...
But now I'm feeling more like when my time comes to cross, i want my tattoos cremated with my body. I'm taking them with me to the other side.
Tattoos are my spirit armour. Without being "lived in", well, tattoos are just pictures on dead skin and lose the meaning if I am not alive. Just me personally. This belief is dynamic, just like the meaning behind all my tattoos.
