Peter Bills: Evergreen Player points the way for modern-day stars
For a sport that does not involve a single tackle and never sees a ball fired or struck at an opponent, golf is extracting a heavy toll on its participants.
Tiger Woods' recollection this week of the fact that he has now had four operations on his left knee, a torn Achilles and a broken leg, was followed by fears that young Northern Ireland star Rory McIlroy could be facing long-term problems with his back.
A bad back? That's society's most common complaint, but we're dealing here with what we thought were super-fit sporting icons, men whose bodies were in rippling rude health. Seems the opposite is the truth, in many cases.
