Do you honestly feel that you play as good now as you did when you were younger? If you say YES, you would be lying! NOBODY does. Not Efren, not Sigel, not Varner, not Buddy Hall...NOBODY at a certain age.
Stan is NOT a young person with young eyes, or young anything. He's older than you are. What he did and is doing now at his age is INCREDIBLE! Screw what he did when he was young because he no longer is.
His game and skill level now is a direct by product of learning, refining, and using CTE whether you like it or not. It has rejuvenated and extended his pool playing years to a level that few men have at his age or younger.
No of course not -- I'm playing better now than I've ever played in spite of bad knees and cataracts.
However, Stan, like the rest of us, plays based upon the foundation of decades of playing. I was in Mexico recently and played in a 3C tournament there and could barely see the edge of the balls 10 feet away. BUT my experience told me were the edges were and I did OK.
