as Cracked puts it - B.S. headline of the week!
1/ It's not news, it is a press release by anti-fluorine activists
2/ It's nto a given - it is a possibility
3/ The levels that constitute "high" are those on poluted Indian and Chinese weater supplies that are up to 20 times allowed levels in "normal" drinking water
and as a bonus it is written with Cracked/com's usual reliance on humour
