(CNN) - Commenting on the controversial change in the rules of golf–the upcoming ban on anchored putting–former President Bill Clinton opened up about his hand tremor while elaborating on how he could benefit from the new rule.
"I have a condition that sometimes you get with aging," Clinton said. "You may have noticed it; my hand has a little tremor when I'm tired and a lot of people do when they're older."
"The first time it happened," he continued. "I had to go get myself checked to make sure I didn't have Parkinson's (disease), and I was so relieved (with a negative diagnosis) I didn't care how much it shook after that."
Clinton told CNN's chief medical correspondent Dr. Sanjay Gupta in 2009 that he had been tested for the disease after feeling "quite concerned" when he noticed his hands were shaking at times.
"Because if I had Parkinson's, I wanted to know so I could prepare. And I had it tested and the doctor said 'no.' He says it's just a normal aging phenomenon," the former president said.
Lifting both hands, Clinton showed the tremor to Gupta.
"See, it's a little shake," he said.
In his most recent comments, Clinton was speaking in Palm Springs, California at an event associated with the Humana Challenge golf tournament, whose sponsors include the Humana health care company and his Clinton Foundation.
Anchoring the putter grip in one's belly may give players an advantage, supporters of the rule change say, because it aids players' control of the club on critical shots. Opponents say an anchored club is not swung in the spirit of the game.
While the rules may be changing soon, Clinton said he won't really miss the putting club.
"I've never been able to figure out how to use one of those things so I don't care," he said.
