Any "eaxpert" that would conclude that this was blood or blood vessels (Its hard to follow your logic), That expert is an idiot.
Jumping to uch outrageous concluwsionsw without any definitive evidence iw stupid. As I said before (And you are obviously so caught up with your "blood " delusion that you cant even see other options that really make more inorganic sense).
Mineral "habit" is a stidy in itself and to deny that just defines your delusions.
Carry on, at least you are funny
(Along with your "experts")
