Dr Paul Thomas once bubbled...
At least piercing just leaves a scar!
Odd indeed that we in the West are now developing self mutilation to a fine art. We do have quite a way to go, however:-
I seem to remember the males of some African tribes used blocks of wood to enlarge their (pierced) lower lips while in another tribe metal rings were worn around the necks of girls to elongate the neck. Also I have seen pictures of bones worn in noses.
All for the sake of "beauty"?? :bonk:
As for navel piercing, sadly, youth will not accept advice of elders. They must always find out for themselves the hard way!
By the way Walter, there are nasty critters in fresh water too but I guess fewer fresh water dive sites come with their own sewage outfall. (I remember saluting Admiral Brown many times in the Tay Estuary off Monifieth! Victorian plumbing has a lot to answer for!)
