I recognize and appreciate that cuesports allows for longer primes than more physically demanding sports. Hoewver, that does not mean its participants do not undergo normal age-related decline. It just means that said decline does not remove participants from high-level competitioon as rapidly.
Even that list betrays the reality--it's weighted quite heavily towards the younger side, with only two folks over 51 still on the tour. Twenty years ago, how many snooker players were between 20 and 40 (those from 40-60 now)? Where did the rest of them go? Of the players on the list, how many are still playing their personal best?
My comment was nothing against Shane. It's just reality. Father time is undefeated. Shane is already losing stamina. He's close to as good as he ever was, but he's not going to get better and age says he will not stay the same. He will regress, just rather slowly compared to athletes in other sports. I'm not sure that point is arguable.
