So by now your thinking' What the bloody hell is he on about, whats this got to do with S&P section!' The Russians had been using this technology since the 50's to improve their athletes performance in the Olympics, and their legendary ice hockey team which beat the Canadians only after 5 years of training, Negative ions can increase endurance by up to 900% and as well as improved sleep, mood, help with chronic migraine etc. Heres some websites that sell the machines: High Density Negative Ion Generator (Ionizer) Ion House - Ion Trading (Japan) The Olympic report: Special Olympic Report: Secret Russian Sports Weapon Disclosed What do you guys think?
