"I ride a motorcycle when I'm home in Los Angeles," the leading man, asked if his motorcycle days are over, answers in response to a reader's question in the new issue of Time magazine.
"It's my main mode of transportation," says Clooney, 46. "I've been riding for 30 years, and I've had three accidents, which isn't bad odds. I'll keep riding."
And perhaps inspired by Brad Pitt's recent comment that when it came to running for President of the United States, "George should do it! He'd be quite good," Clooney says he'll never toss his hat into the ring.
"No," he says. "As an advocate, I can take a side and stand by it and not have to worry about ticking off some constituents who helped get me elected. I don't want all those kinds of strings attached."
Asked if celebrity activism has become cliché, he advises, "You don't want to be a spokesperson unless you are absolutely committed to a cause because you can hurt it. I've been asked to help represent environmental groups. I'm a big proponent of cleaning up the environment. I have two electric cars. But I also have a big weak spot because I've flown on private jets."
He adds, "However, I welcome any of these dumb pundits who make celebrities out to be bad guys to a discussion about Darfur. Because I've been there and I've met all the players, and I guarantee you, the pundits haven't."
Kidman Paid UpOn a lighter note, he acknowledges the $10,000 bet he made with Nicole Kidman and Michelle Pfeiffer that he would still be single when he turned 40.
"Yes, I won that bet. They paid up," he says. "When Nicole sent me the check, I sent it back and said, 'Send it to charity.' "
Finally, asked about the loss of his beloved pet pig, Max, who died of old age last December, Clooney says he'll decline on finding a successor.
"There is only going to be one pet pig in my life," he says, laughing. "I have done the pig thing."
