Several reasons explain aging. The first is evolutions lack of good timing: we get old after having children and evolution has no need or timing to push back our aging. We have had our children and therefore are not needed any longer to keep the species going. Secondly, whatever the evolved solutions might have been they are simply too late. Too soon old and too late smart coupled to our metabolism make us un-necessary, the species has been preserved. We have a longevity problem because the stem cells fail to keep homeostasis well and functioning. So we die and demonstrate our irrelevance for the generations behind us.
