As we get older we sometimes begin to doubt our ability to "make a difference" in the world.  It is at these times that our hopes are boosted by the remarkable achievements of "seniors" who have found the courage to take on challenges that would make many of us wither.

 
Harold Schlumberg is one such remarkable person: - a living legend.
VERY INSPIRING!

   
 
"Ive often been asked, What do you old folks do now that youre retired?

 
Well.... Im fortunate to have a chemical engineering background, and one of the things I enjoy most is turning beer, wine, Scotch, and margaritas into urine."
