I'd like to know if any reputable scientists are pursuing the genetic angle. Why are these "free radicals" created? Do you think that maybe the body is genetically programmed to limit it's own life?
free radicals are a natural product of energy production in the body. The question is: why body defenses aren't adequate to remove them.
What is most important here is that science now understands the reason for the general damage of aging - free radicals in the cells mitochondria - that's where antioxidant therapies are being focused - and some of the new artificial antioxidants are quite promising.
