It highly depends on the definition you use, gather them from wikipedia and a few dictionaries and you will see. Looking at it from different languages is also worth looking into. I see it as an unavoidable (so far and in my opinion for a long time) disposition to go through a process. As such I would not consider aging in general as a disease. But individual processes taking place in aging would be in my opinion, especially since they can happen at earlier age in some people. I am much more interested in providing better quality of life to people impacted by those than to everybody (the societal impact would be quite dramatic).
