When I was 55, I was walking and 3 8-9 year old kids came speeding by on their bikes. One said to me, "watch out old man!" - that was amazing but now I fit that; old, now hey 3 score and 10 years :) Stroke, blood clot in leg, minor pneumonia, but I'm not bitter. I saw a teen at rehab doing PT. He had no use of his legs so I have nothing to complain of. You anti-stem cell ppl should feel ashamed of yourselves, vote for OBAMA as many times as you can :)))
