Paris Hilton warns teens of the perils of drinking and driving in the December issue of Seventeen mag. "All it takes is one drink to mess with the way you drive - it clouds your judgment and slows your reflexes," the socialite says just a month after her arrest for DUI. "Don't take any chances. It just isn't worth it." Hilton also blesses teens with the info that she doesn't think she's reached her sexual peak. "I think you like [sex] when you're like, in your thirties," she says. "That's what someone told me. We'll see."
