Capsaicin is not the only thing that is bad for you! ========================================================= Little known toxic properties of the element oxygen: In concentrations of greater than 75% this element has been shown to cause inflamed mucus membranes, resulting in lesions that resemble first degree burns. This element has also been shown to be dramatically toxic in very low concentrations. Prolonged exposure to concentrations below 0.1% are invariably fatal to the test subject. The most common range of exposure, however, is between 20 and 22%. This causes a slow degradation of the vision, hearing, muscular strength, flexibility and in the case of the male, potency, ending in eventual death. The process is commonly referred to as aging.
