Interviewer Charlie Rose remarked that some may think Hillary Clinton's health is a campaign issue given her cough on the campaign trail and her pneumonia diagnosis.
"They think everything is a campaign issue," Bill Clinton said in the interview broadcast on "CBS This Morning."
"I think her lifestyle and underlying indicators, from blood pressure to amount of exercise to everything else, means it's almost certain she's in better health than her opponent," he continued. "But we don't know, because he hasn't disclosed."
The Clintons have played down the health scare involving the Democratic nominee on Sunday, when she stumbled and was held by aides while leaving a 9/11 memorial early.
"She just got dehydrated," Clinton told CBS.
Rose mentioned video of Hillary Clinton stumbling while being helped by aides into a van on Sunday, asking if it was more serious.
"If it is, it's a mystery to me and all of her doctors," Bill Clinton insisted. 
"She's worked like a demon, as you know, as secretary of State and as a senator and the years since," Clinton said. 
Hillary Clinton on Monday night said she didn't think her pneumonia diagnosis was "going to be that big a deal" after her campaign waited until Sunday evening, after she left the memorial, to disclose the Friday diagnosis.
Bill Clinton, 70, told CBS that he feels that he is in good health.
"I just had a physical not that long ago and I passed with flying colors," he said.
