jimbo, the third sentence of your second link gave a good summary as follows: "If the generation of free radicals exceeds the protective effects of antioxidants, and some co-factors, this can cause oxidative damage which accumulates during the life cycle, and has been implicated in aging and age related diseases......."
But I think this may lead to more questions such as, "how much is enough with respect to antioxidants?" Exactly how many free radicals are being produced, by a particular individual, from stress and/or overexercising. Will we ever know for sure if we have it under control? Is there any amount of antioxidants that will prevent all oxidative damage? I doubt it. Perhaps the only true test result is to stay healthy.
