How about this bizarre story? -

75 year old guy has made it a life's work to give blood as much as possible. He will become one of only two persons in the U.S. (probably also int he world) to have donated 40 Gallons(!) of blood in his lifetime.
Now, while this is probably altruistic in a way, I am reminded of those ladies who collect about 150+ stray cats or dogs and keep them in their old house, or perhaps those nut-jobs who were running a 150 mile marathon across the Death Valley desert in full summer at 115 degree temperatures.
There is a reasonable limit to all good things. Wonder if this will make the pages of the revised Awake magazine?
