I'm guessing that a lot of people don't go on the longer runs because they are older! I know that in MY case , I can't do the things that I used to because I am an insulin dependent Diabetic! Also I have to take so many pills that you would GAG just thinking about it. Plus I finally realized that you have to take care of your health & not live on Booze & a "who cares" attitude! It only took me 71 yrs to get some sense , so many people don't do the crazy things & pay attention to the things that they should!
