Greatness

Watching two Ufc legends go to battle was truly awesome yet very thought provoking. When do you call it a day? What should decide the time? I think seeing Coleman a shell of him former self has to show us all our own mortality. I know Coleman well as a fan having watched him in his glory days with awe, who wouldn't. He dominated with more meaning then even Royce because of competition restraints protecting Royce. He thourghly dominated our sport like no other, so seeing his slide really highlights my own mortality. To be honest it's rather depressing seeing father time break down such greatness, it shows the inevitabilty of losing greatness. The question knaws at me as to what does this life mean if greatness is so fleeting?
