johnnydoom One of the golf magazines came up with a mathematical formula for whether you would be able to do it... I don't remember all the specifics, but I can tell you that unless something drastically changes, your chances approximate zero.
The reason it is so hard to do is that, in general, golfing scores worsen with age. Sure, you can occasionally shoot 81 now, but when you are 81, even if you are still out there playing, it will have become a lot more difficult to shoot 81.
I can't remember the percentage of players who are able or will potentially become able to shoot their age, but it was very, very small.
