So to clarify, I think there is merit in his approach of trying to engineer solutions to age related pathology. However, I do not think it will work for all aspects of aging right now. Aubrey believes that all the damage caused by aging are problems that we can begin solving right now. I would suspect that some are hard problems that will require a better understanding of the biological mechanisms involved before we can treat them.
So my position is that aging, like many fields, should be investigated both at the basic biology level and the from the perspective of trying to design therapeutics, because you don’t know if you can fix problems with current knowledge unless you try. However, if you fail to adequately treat the condition you want basic research to be ongoing.
