I don't think golfers are in the same universe as those other sports and what it does to the body. Many golfers come into their own in their 30s, and Phil Mickelson has been better after 35 than before. Look at what Vijay did in his 40s. Hell, Tom Watson was a bad chip away from winning a major championship when he was months away from 60 years old. There are countless examples.
Golf does have some impact on the body, but overall it's not something that will cause a body to break down. The most common physical ailment for golfers in back problems. A golf swing does place a lot of stress on the back over the years. But Tiger's body breaking down has ZERO to do with any of this. It's his knee. Abnd he saw this coming from the beginning of his career. Most people thought he was nuts to walk away from Butch and go through a swing change early in his career because he was so dominant. A big part of why he did it was because he knew his knee would not hold up if he continued to swing the way he was swinging.
