Let's be honest. This was an anomaly. It's doubtful that there will be anyone over the age of 55 with the lead heading into a Sunday at the British Open in the near future.
Even so, we are in a new age of golf where players are fitter than ever before. Tom Watson is a prime example of one of the Champions Tour players--Jay Haas included--who has continued to keep himself in shape. Who knows...Vijay Singh or Kenny Perry--both of whom have played their best golf over the age of 40--might be playing this well in 10 years.
And how about Camilo Villegas when he gets to the 50-and-over club? He might lose some distance, but a lot of that muscle won't be going anywhere. Just ask Gary Player, who can still do push-ups at his age.
Taking into consideration advances in technology, wouldn't it make sense for the R&A to bump the age back up to 65? Hopefully Tom Watson makes the cut next year at St. Andrews and that will send the message home. He'll be a young 60.
