Aging is an illness, a degenerative process for which evolution has optimized against by reproducing before it takes its toll (death). It is entropy maximizing, dissolving the body. Those processes can be reverted by correctly directing outside energy into the system, in order to achieve reordering (reduce entropy); we just need to find the proper way to do it. Once we find the root cause of aging, and we devise a cure for it, we will be surprised at why it took so long to understand such a simple problem. The same way we are surprised to hear that people 200 years ago were convinced that heavier-than-air objects could not fly, or that trains traveling at high speed (50 Km/h) would cause irreparable damage to the body.
