The gerontological medical literature is filled with references to the importance of oxidative damage in aging. Yet antioxidants repeatedly have been found to exert little or no effect on maximum lifespan in mammals. Various explanations for these unexpected results have been sold in medical journals. However one large fact counters these quite effectively. Guess which animal's cells have more antioxidants? 1. A mouse with a 3 year lifespan. 2. A human with a 100 year lifespan. That's right, the answer is 1. Human cells are nonetheless far more resistant to the damaging effects of oxidants, and it is this property that just might have something to do with the human's 30 times greater lifespan.
