Can you improve another 25-50?
Short answer: yes.

70 and still improving
I guess father time comes a-callin' for us all...but I think the game can be rewarding for years to come...at least my 46 year old brain wishes for this to be the case. The excerpt below is from Onepocket.org's interview with George "The Trapper" Rood, a legendary player in his own right. Rather than mourning the "failure" to run 90 on his 90th birthday, I find hope that he was even trying! I can only hope for such a fine outcome for myself, though my high run goal at an advanced age will be a touch lower...

There is a consolation prize in trying one's best regardless...the pursuit can be its own reward regardless of outcome. That's my 2 cents.
"OnePocket.org: Well George, you are an inspiration to all these younger guys that are 9-Ball players and are taking up the game of One Pocket when you were — how old were you when you took up One Pocket?
George Rood: 75 or 80.
OnePocket.org: 75 or 80; so it is never too late!
George Rood: Well at 75 I could still run out the balls pretty well, especially Straight Pool. I haven’t tried lately, but I tried to run 90 on my 90th birthday and I didn’t get it done. I have to admit a failure.
OnePocket.org: Well, maybe you’ll make up for it next year if you run 91.
George Rood: There you go. The last run I made more than my age was 126 a couple of years ago. That’s a pretty good run for an old man. They had a One Pocket tournament the other day and I was playing. I was one in the hole and they had seven. And I made a shot and ran nine and out. The other guy broke the balls and I ran eight and out. I broke the balls, made one on the break and run three more, so I ran 21 balls.
OnePocket.org: So you ran nine, eight, and then four, at 90 years old!
George Rood: Yeah, that’s quite a few in One Pocket."
