Every year tens if not hundreds of thousands of people die from complications of influenza, a disease that has caused more deaths in human history than any other and also the cause of the most lethal global pandemics and plagues. The Spanish flu if 1918 killed % of the world and was only 20% fatal. Evolving failures of lure pecially the H5 avian stains can be up to 90% fatal in humans and the failure of the flue vaccine and suppression of ascorbate as a treatment (legal only in New Zealand) borders on criminal especially when you take into account the way government have been strong arm into stockpiling the patented drug Tamiflu (from one of Rumsfeld's companies) which doesn't work as well as vitamin C tablet you can buy from a gas station.

A lot of these are preventable deaths.

There has never in all of human history ever been any harm shown from fluoride other than overdose. In the worlds worse case of fluoride overdose there was zero damage of any sort and the patient recovered normally and was just fine.
